• Highly reliable for use in high-temperature environments up to +150 °C

TDK Corporation (TSE: 6762) has expanded its TFM201612BLEA series (2.0 x 1.6 x 1.2 mm – L x W x H) of thin-film power inductors for automotive power circuits to higher currents up to 5.6 A. The two new components have a rated inductance of 0.33 µH and 0.47 µH, respectively. Mass production of this product series began in July 2025.

In recent years, demand for inductors for automotive power circuits has continued to increase as electric vehicles and ADAS for safe driving have become more widespread. Highly efficient power supply circuits are necessary to lower energy consumption, driving the development of low-loss, high-efficiency inductors. Inductors for power supply circuits must be compact, as they need to be installed within the limited space of ECUs. High reliability is also crucial, as they must operate in harsh, high-temperature environments.

Compared to the conventional TFM-ALMA series of the same size with an inductance of 0.47 µH, this new product achieves a 16% higher rated current of 5.6 A and a 31% lower DC resistance of 22 mΩ, offering the highest standard* of electrical performance. This helps to reduce loss and to improve efficiency for power supply circuits, enabling support for high-current applications within the same footprint as conventional models. Additionally, the inductor ensures high reliability with an upper operation temperature range limit of +150 °C, thanks to a product design assuming use in high-temperature environments in automotive applications.

With TDK’s proprietary materials and structural designs adapted to the diverse needs of automotive power circuits, TDK will work to expand its comprehensive lineup, utilizing not only thin-film technology but also wire-winding and multilayer processing technologies, thereby contributing to the enhancement of the quality of automotive power circuits.

TDK Corporation (TSE:6762) has expanded its MEMS inertial sensors portfolio with the Tronics AXO315^®T0, a high-temperature MEMS accelerometer with ±14 g input range and a digital interface for measurement while drilling (MWD) applications in the energy market.  

Leveraging TDK’s unique closed-loop architecture that provides an unprecedented level of vibration rectification and resistance to operational shocks, AXO315T0 exhibits a bias residual error of 0.8 mg over its operating temperature range of -30 °C to +150 °C, enabling a precise and continuous inclination measurement for directional drilling tools exposed to high temperatures. 

To cope with the stringent reliability constraints required to maximize the productivity of complex drilling operations in severe environments, TDK has qualified AXO315T0 through extensive reliability testing. This includes more than 1000 hours of powered life testing at +165 °C, temperature cycling from -55 °C to +165 °C, as well as high temperature vibration tests (20 g RMS random vibration combined with 50 g sine sweep). 

With a typical bias drift of less than 1 mg without recalibration after 1000 hours at high temperature, AXO315T0 brings a digital and low-SWaP alternative to legacy quartz accelerometers, paving the way for a new generation of MWD tools able to operate for long periods at high temperatures with no compromise on performance. 

AXO315T0 sensors and evaluation boards are available for sampling and customer evaluations. TDK will further expand its MEMS portfolio for the energy market with a new accelerometer withstanding operating temperatures up to +175 °C. 

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.
