Using metallic magnetic material as a core material, the inductors were downsized by about 35% compared to those that use ferrite material with similar attributes, TDK said. The inductors feature a temperature range of -55° C to 155° C for support in extreme conditions.
The AEC-Q200 qualified inductors are designed for a range of electronic control units including those for advanced driver assistance systems (ADAS).
TDK said vehicles are increasingly using an electronic control unit for information communication and self-driving features, leading to an increase in the number of inductors for power supply circuits inside these units.
TDK said mass production of the BCL322515RT will begin later this month.
