SPM-CT Series Power Inductors

TDK's SPM-CT series magnetically shielded, wirewound inductors are ideal for power circuits. Compared to conventional SPM series products, the SPM-CT type offers high Q characteristics in the high-frequency region, thanks to a proprietary alloy powder. They also offer large current specifications, low R_DC, and compactness compared to ferrite-wound type inductors. SPM-CT inductors have lower hum noise than the core adhesive coils, made possible using metallic magnetic material and an integrated molded coil structure.

SPM-CT series inductors are available in sizes ranging from 7.1 mm x 6.5 mm x 5.0 mm to 13.0 mm x 12.5 mm x 6.5 mm with an inductance range of 220 nH to 500 nH with ±15% to ±20% inductance tolerance. They are available for use in applications such as wireless charging, notebook PCs, HDDs, servers, VRMs, and more.
