TDK SPM6550CT Inductors
TDK SPM6550CT Inductors are magnetic shield type and are designed for power circuits using a metallic magnetic material. These inductors feature low inductance variance in high-temperature environments with excellent DC superimposition characteristics. The SPM6550CT inductors have lower hum noise compared to the core adhesive coils. This is made possible with the use of metallic magnetic material and an integrated molded coil structure. These inductors consist of high Q characteristics in the high-frequency region that help in realizing low loss. The TDK SPM6550CT inductors are available in two variants with inductance values of 0.33µH and 0.50µH. Typical applications include HDDs, servers, and compact power supply modules.
