SPM-LR Wound Metal Inductors for Power Circuits

TDK SPM-LR Wound Metal Inductors are designed for power circuits. These magnetic shield-type wound inductors are low profile, with packages as small as 3mm x 3mm x 1mm. The SPM-LR series achieves higher current and lower resistance than ferrite wound-type inductors. The inductors also provide low inductance variances in high-temperature environments up to +125°C. TDK SPM-LR Wound Metal Inductors feature an integrated molded coil structure that keeps hum noise lower than with core adhesive coils. Typical applications include tablet terminals, laptop computers, servers, and more.
