INDUCTORS Inductors for power circuits Cl Pb Br Wound metal REACH Halogen Lead RoHS SVHC-Free Free Free SPM-LR series SPM3012-LR type FEATURES Magnetic shield type wound inductor for power circuits using a metallic magnetic material. Low-profile product. Compared to ferrite wound type inductors, it is possible to achieve large current, low Rdc, and compactness. Low inductance variance in high-temperature environments with good DC superimposition characteristics. Metallic magnetic material is used, and the structure has an integrated molded coil, so hum noise is lower than with core adhesive coils.
