TDK Corporation (TSE:6762) launches the ADL8030VA, a high-performance inductor designed specifically for power-over-coaxial (PoC) applications. Due to its high impedance over a wide frequency range, this component streamlines the PoC filter design by requiring only one single component instead of the conventional approach with two or more inductors. This significantly reduces complexity and cost in advanced driver-assistance systems (ADAS) and other automotive electronics, where space efficiency and reliability are critical. With the ADL8030VA, TDK is once again driving mobility transformation toward a more connected and safe future.

In standard configurations, ADAS sensors like automotive cameras require two separate lines: one power line connected to the battery and a signal line connected to the electronic control unit (ECU). However, with PoC technology, a single coaxial cable can simultaneously carry both power and data, simplifying and reducing the wire harness.

The 7.8 x 2.7 x 2.7 mm (L x W x H) small ADL8030VA series offers inductance values from 10 µH to 100 µH with a rated current range of up to 0.82 A, ensuring robust performance from -55 °C to +155 °C across a wide frequency spectrum. Its low DC resistance of less than 0.5 Ω for the types with 22 µH or less minimizes power losses, enhancing overall energy efficiency. Its compact design is engineered with a ferrite core, enamel copper wire welded to the terminals, and flame-retardant molding. It offers high mechanical stability and meets AEC-Q200 qualification standards, ensuring durability under harsh automotive conditions.

• New 35-V products with 0.22 µF in 1005 size and 10-V products with 4.7 µF in 2012 size for automotive applications added to the lineup
• Contributes to the reduction of component count and the miniaturization of sets as well as reduces voltage fluctuation and high-frequency noise
• Qualified based on AEC-Q200

TDK Corporation (TSE: 6762) has expanded its YFF series of 3-terminal filters for automotive applications to include higher voltages up to 35 V and higher capacitances up to 4.7 µF. Such components are used to suppress voltage variation and high-frequency noise, which can cause system malfunctions. Mass production of the product series began in June 2025.

With the miniaturization of automotive electronic systems, there is an increasing demand for measures to prevent system malfunctions. Usually, numerous capacitors are employed in such applications. On the other hand, the number of components must be reduced due to the miniaturization of these systems. To address these challenges, 3-terminal filters, characterized by a low ESL (equivalent series inductance), are gaining significant demand.

By optimizing the material selection and product design, the new products feature significantly higher withstand voltage, ranging now from 6.3 V to 35 V, and considerably higher capacitance, ranging now from 0.47 μF to 4.7 μF. The 35-V product with an insertion loss of 40 dB (4 MHz to 2 GHz) can be used for a broader range of power lines, including both input and output of power-supply systems, while the 4.7 μF product with an insertion loss of 30 dB (300 kHz to 3 GHz) is more effective as input capacitors than conventional products in reducing voltage fluctuation and countering high-frequency noise. Moreover, depending on set usage conditions, it is possible to halve the component count required to suppress voltage fluctuations to the same extent from the MLCC.

• Compatible with currents as high as 8 A
• Saves space by reducing components and footprint
• Highly reliable for use in high-temperature environments like automotive and industrial applications

TDK Corporation (TSE: 6762) has expanded its MPZ1608-PH series of large-current multilayer chip beads for automotive and commercial power supply lines (1.6 x 0.8 x 0.6 mm – L x W x H). Mass production of the product series began in May 2025.

These 1608-size chip beads for power supply lines achieve a rated current of 8 A, the industry’s highest value*. Chip beads are used as noise suppression components in power and signal circuits. In a circuit with a current of 8 A or more, usually two or more chip beads must be used in parallel. This has the disadvantage that the current is not evenly distributed between the ferrite beads. TDK’s new product simplifies the circuit structure because fewer components are required compared to conventional methods, and it improves the quality of power circuits.

The MPZ1608-PH series of products halves the component footprint in comparison with circuits using two conventional 1608-sized chip beads. Moreover, the highly reliable components with a specified operating temperature of up to +125 °C are designed to be used in high-temperature environments like automotive and industrial equipment applications.

With TDK’s proprietary materials and structural designs adapted to market needs, the company is committed to expanding its lineup of high rated current products in the automotive, industrial equipment, and consumer equipment areas. These chip beads will serve as EMC components contributing to the enhancement of the quality of power circuits.

TDK Corporation (TSE: 6762) has expanded its CGA series for automotive multilayer ceramic capacitors (MLCCs) to 10 µF at 100 V in 3225 size (3.2 x 2.5 x 2.5 mm – L x W x H), with X7R characteristics (Class Ⅱ dielectric). This is the industry’s highest capacitance* for a 100-V rated product in 3225 size and this temperature characteristic. Mass production of the product series began in April 2025.

While power consumption has increased and high-current systems have become more widespread in recent years with the increasing sophistication of ECUs, there is also demand for lighter vehicles (with lighter wiring harnesses), and the use of 48 V battery systems is becoming increasingly widespread. With this, there has been an increasing demand for high-capacity 100-V products, such as smoothing and decoupling capacitors used in power lines. 

CGA series 100-V products achieve twice the capacity of conventional products of the same size thanks to optimized material selection and product design. This new product makes it possible to halve the number of MLCCs used and the mounting area, contributing to the reduction of component count and miniaturization of sets. TDK will further expand its lineup to meet the needs of customers.
