The recent hike in precious metal prices is putting commercial pressure on conventional multilayer piezo designs that use silver. In addition to increasing costs, silver is the primary cause of failure when moisture is present. By using copper instead of silver, TDK offers a compelling solution to both challenges.

As of early March 2026, the price of precious metals was near record highs. Silver has surged by more than 100% in the past six months [1] (Fig. 1a). In such a turbulent market, TDK’s patented High Active Stack (HAS) technology [2], which is copper-based, shields manufacturers from both relentless price escalation and supply-chain instability. This is because the price of copper has increased by just 29% in the last six months [3] (Fig. 1b). This makes the high-performance HAS technology more accessible and economically sustainable.

Additionally, silver-based electrodes come with a technical drawback: they are susceptible to moisture, also known as silver migration. This can lead to reduced endurance and potential short circuits in the components, compromising reliability in damp environments. Unlike silver electrodes, copper electrodes are inherently resistant to this effect, delivering greater durability and reliability. TDK’s third‑generation copper‑stack actuators demonstrate this advantage with an exceptional lifespan of over 100 million cycles at +85 °C at 85% relative humidity, energy‑controlled for nominal elongation. This performance is made possible by a patented copper‑etching process that significantly enhances both lifetime and structural robustness.

Broad applications across industries

For over 20 years, TDK’s HAS actuators have been an integral part of automotive fuel injection systems. But they are not limited to cars. They power nano-positioning systems in semiconductor production, ensuring accuracy in wafer handling and lithography processes. In medical applications, they support devices like ultrasound transducers and drug delivery systems, where precision and humidity resistance are non-negotiable.

The PowerHap series [4], for instance, extends to haptic feedback in consumer electronics, such as wearables and VR equipment, delivering crisp vibrations [5]. Valve controls in process engineering also benefit, managing liquids and gases with exceptional speed.

Furthermore, in AI infrastructure, enabling advanced optical solutions for high-speed, low-latency data transmission in data centers. This supports the massive computational demands of AI, offering humidity-resistant reliability and cost stability essential for scalable, efficient data center operations.

Designing a portable defibrillator, the size of a lunchbox, requires solving an engineering paradox: the smaller the high-voltage capacitor, the more energy it leaks over time. For a device that must deliver a decisive shock after months on standby, such energy loss is unacceptable. As the first capacitor prototypes from different manufacturers showed high leakage current, the question became: could this challenge even be solved?

When engineers at Corscience set out to create the world's smallest automatic external defibrillator (AED), they faced a fundamental engineering paradox: they needed a high-voltage capacitor that was both incredibly compact and remarkably reliable. The challenge would require more than off-the-shelf components; it demanded innovation at the material level. The specifications set by the defibrillation experts from Erlangen were demanding: stable capacitance at 2 kV, delivering the required therapeutic level of stored energy through a biphasic truncated exponential discharge.

But size wasn't the only constraint. It’s crucial for a defibrillator that the capacitor maintains its charge over extended periods. Any significant leakage current could mean the difference between a functioning defibrillator and a failed rescue attempt. "It is literally vital that the AED is still able to provide the energy for defibrillation after months in standby at different ambient temperatures, like in your car," explains Manuel Seufert, Team Lead Defibrillation, Shock & Analysis at Corscience.

An automated high-voltage capacitor test bench was used for a comprehensive evaluation of all relevant capacitor parameters

This requirement created a classic engineering trade-off for TDK: thinner dielectric foils enable smaller capacitor dimensions, but they also increase leakage current. Aluminum electrolytic capacitors require series connections with balancing resistors that continuously discharge the stored energy – unacceptable for this compact AED. Ceramic capacitors face similar limitations. Only film capacitors could meet the demanding voltage and reliability requirements and were the clear choice over ceramic or electrolytic alternatives. To verify this, Corscience developed an automated high-voltage capacitor test bench. The system enables comprehensive evaluation of all relevant capacitor parameters across large sample sizes and under varying temperature conditions. However, initial samples from several manufacturers either exhibited excessive leakage current or exceeded the allowable dimensions. As a result, moving forward required close and in-depth collaboration.

TDK and Corscience sat down to dissect the requirements in detail, combining TDK's expertise in capacitor manufacturing with Corscience's extensive experience in defibrillation technology. The second iteration samples were significantly better than comparison types from other manufacturers. "Our collaboration has been a remarkable fusion of innovation and purpose," notes Anderson Estancovich, the product marketing manager responsible at TDK. "Together, we've not only engineered the smallest AED on the market but also redefined what's possible in medical technology. This makes critical care more accessible, discreet, and patient-friendly than ever before." The partnership extended beyond just component development. Corscience supported the implementation of a dedicated test bench for future high-voltage capacitors at TDK, enabling real-world simulation and validation of long-term stability.

• TDK establishes Asia-Pacific Regional Headquarters (APAC RHQ) in India, effective 1 April 2026
• APAC RHQ will be operated by TDK Asia-Pacific Pvt. Ltd., a new legal entity to be established in India, and TDK Singapore Pte. Ltd., forming a dual-city administrative structure
• The RHQ is part of ‘TDK Transformation’, the company's Long-term Vision

TDK Corporation (TSE:6762) announces the establishment of its Asia-Pacific Regional Headquarters (APAC RHQ) in Bengaluru, India—the company’s fifth regional headquarters alongside Japan, Europe, the Americas, and China. The new legal entity, TDK Asia-Pacific Pvt. Ltd., together with TDK Singapore Pte. Ltd., will govern more than 20 TDK entities across India, Southeast Asia and Oceania—representing nearly 17 percent of TDK’s 105,000 team members. Effective 1 April 2026, the APAC RHQ will operate from a dual-city administrative structure: Bengaluru, India, and Singapore, together the epicenter of one of the world’s most consequential economic corridors and drive ‘TDK Transformation’.

Asia-Pacific is the growth market of this century. Home to nearly 40 percent of the world’s population, the region is projected by the IMF to grow at 4.5 percent in 2025, contributing roughly 60 percent of all incremental world output—even as global growth holds at a modest 3.2 percent. Within it, India stands decisively apart: at 6.6 percent GDP growth for FY2025/26 (IMF), the fastest-growing major economy on earth for the third consecutive year, and now the world’s fourth largest after surpassing Japan in 2025. For TDK, this is familiar terrain approached with new ambition. The company has operated in India for several decades, through its two principal business entities—Electronics Components Business Company (ECBC) and Energy Solutions Business Company (ESBC)—and their subsidiaries, with production facilities in West Bengal, Maharashtra, and Haryana. Today, TDK in India employs over 5,000 people.

"With the establishment of the Asia-Pacific RHQ, we are not simply expanding our footprint—we are strengthening the foundation for the future”, said Vaidyanathan Ramasarma, General Manager, APAC RHQ – TDK Corporation. “This region holds immense potential in technology, talent, and market development. Our mission is to unlock that potential responsibly, collaboratively, and strategically.”

The dual-city administrative structure will balance growth and governance equally in a region that demands both. Bengaluru anchors the growth agenda—India’s technology capital with one of the world’s deepest talent ecosystems in engineering, and foundational research, positions TDK to build new categories, not merely optimize existing ones. The APAC RHQ will invest in emerging technology domains, leveraging India’s tradition of frugal engineering and favorable unit economics for a growing global marketplace. Singapore anchors governance, compliance, and supply chain—a trusted, neutral fulcrum for a region of extraordinary complexity. Together, the two cities form a strategic dyad: one looking inward at the intricacies of regional operations, the other at the horizon of what is possible.

The APAC RHQ will strengthen market intelligence, government relations, and supply chain resilience across the region while driving internal efficiencies, workforce skilling, and disciplined process governance—the less visible but indispensable work of building a business that lasts. In particular, APAC RHQ will play a critical role in building TDK’s global R&D network. India’s scientific talent, its appetite for foundational research, and its unique ability to apply deep knowledge to real‑world constraints make it an indispensable part of our global R&D vision. The government of India’s urgency and appetite for foreign direct investment, its improving ease of doing business, and its ambitious national technology initiatives create conditions that are, for a company like TDK, genuinely rare.

For the past two years, a quiet but purposeful effort has been underway—building the relationships, the institutional trust, and the operational foundations needed for success. TDK’s nascent APAC team has been forging partnerships across academia, government, and industry in India, establishing the connective tissue of a long-term commitment. 

Through this APAC RHQ, TDK will strengthen its contributions to social transformation from India and Asia‑Pacific, while also accelerating our own transformation.

By stacking or paralleling several FS1525 modules, they can deliver 200 A combined in vertical power delivery designs. This is a novel approach in which the PoL converters are located directly under the FPGA/SoC or ASIC on the backside of the PCB.

Leveraging advanced 3D chip-embedded package technology, the FS1525 integrates all critical components—including controller, driver, MOSFETs, digital core, memory banks, bypass capacitors, and power inductor—into a single component with a footprint of 7.65 x 6.80 mm (L x W). The thermally enhanced architecture with a thermal impedance of 1.4 K/W delivers superior current performance, outperforming conventional solutions at high ambient temperatures while simplifying PCB routing and enabling high-density power architectures.

Supporting input voltages from 4.5 V to 16 V and an adjustable output range from 0.6 V to 1.8 V, the FS1525 is optimized for powering modern low-voltage AI processors, including the core voltage of 3-nm to 6-nm ASICs, and SERDES rails with sub-5mV peak-to-peak ripple. Its low spectral noise performance matches well with DSPs, imaging, and advanced Automated Test Equipment (ATE) applications. Being scalable up to 200 A and designed for vertical power delivery designs, the new µPOL enhances thermal performance and maximizes board space efficiency.

FS1525 has a fast transient response, low ripple, and true differential remote sensing to ensure accurate voltage regulation at the point of load. Digital programmability via I²C and PMBus enables real-time telemetry, adaptive tuning, and fault management for voltage, current, and temperature monitoring, critical for dynamic AI workloads. The module also offers analog Vout settings tailored to leading FPGA/SoCs and ASICs, supporting advanced features such as Altera’s SmartVID for Agilex FPGA series.

The new µPOL module integrates seamlessly with modern computing form factors, including PCIe, VPX, SMARC, and 1U to 3U rack systems, providing high flexibility for system designers. It is already deployed in proven designs for FPGA/SoCs such as Altera Agilex™, AMD Versal™ Edge, and AMD-Xilinx platforms, including Zynq UltraScale+ MPSoC and Versal ACAP, widely used in AI and machine learning applications.

As part of TDK’s comprehensive µPOL portfolio spanning 1 A to 200 A, the FS1525 offers a unified system-level power solution. With plug-and-play simplicity and no external compensation required, it accelerates development cycles, reduces design complexity, and lowers overall system cost. More than a power module, the FS1525 represents a complete power ecosystem designed to drive the future of intelligent computing. Evaluation boards for 25 A and 50 A are in stock at DigiKey and Mouser. Stackable boards for 100 A and 200 A are available upon request.
