TDK SPM Automotive Power Inductors
TDK SPM Automotive Power Inductors are metal composite, wire-wound inductors featuring coils that are integrally molded with metallic magnetic powder. These inductors feature higher current capability, lower DC resistance, and reduced inductance variation at elevated temperatures. The SPM4030, SPM5030, SPM6530, SPM6550, and SPM10040 series operate within a temperature range from -40°C to +125°C, with a measuring frequency of 100kHz and a maximum tolerance of ±20%. Typical applications include note PCs, HDDs, servers, VRMs, and compact power modules.
