SPM Series Power Inductors

TDK SPM Series Power Inductors include commercial and automotive-grade components for different usages, including low-profile options with heights as low as 1mm. Compared to ferrite wound-type inductors, the SPM inductors from TDK enable users to achieve a larger current, lower RDC, and a more compact design. These inductors feature low inductance variance in high-temperature environments and maintain good DC superimposition characteristics. SPM inductors are constructed from metallic magnetic material and have an integrated molded coil that reduces the humming noise more efficiently than with core adhesive coils. Suitable applications for these inductors include smartphones, tablet terminals, laptop computers, HDDs, car accessories, LED, ADAS, and more.
