Hi-temp, high-current power inductors for LED headlights
The new wound inductors are qualified to AEC-Q200 and are initially available in three sizes: 7.5 x 7.0 x 5.4 mm³, 10.5 x 10.0 x 6.5 mm³ and 13.0 x 12.5 x 6.5 mm³. The nominal inductances are between 1 µH and 47 µH, depending on the type. Series production will start in September 2019.
The SPM-VT series is based on TDK’s innovative magnetic material technology, which enables a high magnetic saturation density and a robust design. These metal core power inductors are characterized by superior DC superposition properties in a compact package size and feature a rated current that is approximately two to three times higher than that of comparable high-temperature products based on ferrite core materials.
Modern adaptive LED headlamps typically use a single control circuit to control all LED headlamp functions such as dipped and main beam, daytime running and bend lighting. The DC-DC converters in the circuits of LED headlights use power inductors. As the functionality of the headlamps increases, so does the number of inductors required. The new SPM-VT series meets the requirements of the automotive industry for compact, high-performance power inductors that can withstand high currents and high temperatures. TDK will continue to expand its range of SPM power inductors; for example, the company is offering miniaturized inductors with dimensions of 7.0 x 6.5 x 4.5 mm³ and 5.3 x 5.1 x 3.0 mm³.
