  • Inductors: TDK launches power inductors for automotive power circuits

    Inductors: TDK launches power inductors for automotive power circuits

    December 9, 2025

    TDK Corporation (TSE: 6762) announced today that it expanded the BCL3520FT series of small power inductors for automotive power circuits (3.3 x 3.5 x 2.0 mm – L x W x T). Mass production of the product series began in December 2025.

    Inductors like the BCL3520FT series are used in efficient power supply circuits of ECUs. High efficiency is necessary to reduce power losses because ever more ECUs for ADAS applications are being deployed in cars. This drives the development of low-loss, high-functional power inductors. These components must be compact, as they need to be mounted in the limited space of the ECU. High reliability is also crucial, as they must operate in harsh, high-temperature environments.

    Thanks to TDK’s proprietary metallic magnetic materials and structural designs, the BCL3520FT series achieves industry-leading* electrical properties for 0.47-μH inductors with such small dimensions. Regarding DC resistance, a low 5 mΩ (typ.) resistance has been achieved, approximately 15% lower than equivalent products available on the market. Using a flat wire instead of a standard round wire reduces heat generation and power loss. Therefore, the components achieve a rated current (Isat) of 10 A, approximately 28% higher than other products, facilitating these products’ uses for a range of applications. These high-reliability inductors can be used in high-temperature environments up to +155 °C, the upper guaranteed temperature limit.

    TDK will continue to contribute to society with its broad lineup of low-loss, high-efficiency power inductors for many different high-function applications aimed at achieving autonomous driving through the development of products that meet market needs.

    * As of December 2025, according to TDK
