I N D U C T O R S Inductors for power circuits Wound metal SPM series RoHS REACH SVHC-Free Cl Br Pb Halogen Free Lead Free SPM10040 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. Operating temperature range: –40 to +125 °C (including self-temperature rise) APPLICATION Note PCs, HDDs, servers, VRMs, compact power supply modules, other PART NUMBER CONSTRUCTION SPM 10040 T - Series name L×W×H dimensions 10.7×10.0×4.0 mm Packaging style 1R0 M Inductance (µH) Inductance tolerance CHARACTERISTICS SPECIFICATION TABLE L Measuring frequency DC resistance Rated current Isat (µH) Tolerance (kHz) (m )max.
