Japanese electronics firm TDK has started production of its TFM201612BLEA series of thin-film power inductors for automotive power circuits with currents up to 5.6 A.
The TFM201612BLEAR33MTCA has a rated inductance of 0.33 µH and the TFM201612BLEAR47MTCA has a rated inductance of 0.47 µH.
The new inductors achieve a 16% higher rated current of 5.6 A and a 31% lower DC resistance of 22 mΩ, compared with the company’s conventional TFM-ALMA series of the same 2.0 mm x 1.6 mm x 1.2 mm size. This helps to reduce losses and improve efficiency for power supply circuits, enabling support for high-current applications within the same footprint as conventional models.
Demand for inductors for automotive power circuits has continued to increase as EVs and driver assistance systems have become more widespread. Highly efficient power supply circuits are required to limit energy consumption, driving the development of low-loss, high-efficiency inductors.
Inductors for power supply circuits need to be compact for installation within the limited space of electronic control units (ECUs). They also need to be highly reliable to operate in harsh, high-temperature environments. TDK’s inductors have an upper operating temperature limit of 150° C.
The main applications for the inductors include automotive power circuits, ADAS, EVs, automotive camera modules and cellular vehicle-to-everything (V2X).
TDK plans to use its automotive power circuit materials and structural designs to expand its product lineup, using wire-winding and multilayer processing technologies in addition to thin-film technology.
