INDUCTORS Inductors for power circuits Cl Pb Br Wound metal REACH Halogen Lead RoHS SVHC-Free Free Free SPM series SPM10040XT type FEATURES Magnetic shield type wound inductor for power circuits using a metallic magnetic material. 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. APPLICATION Power supply around the CPU, HDDs, servers, VRMs, compact power supply modules, other Application guides: Smart phones/tablets PART NUMBER CONSTRUCTION SPM 10040 X T - R18 M LWH dimensions Inductance Internal Inductance Series name Packaging style code tolerance 11.510.04.0 mm (H) CHARACTERISTICS SPECIFICATION TABLE L Measuring DC resistance Rated current Part No. frequency Isat Itemp (H) Tolerance (kHz) (m )max.
