INDUCTORS Inductors for power circuits Cl Pb Br Thin-film metal magnetic material REACH Halogen Lead RoHS SVHC-Free Free Free TFM-ALVA series (for automotive) AEC-Q200 TFM252012ALVA type FEATURES By using metal magnetic material with high Saturation magnetic flux density the excellent DC bias characteristics needed for inductors for power circuits can be achieved. With the same product shape and terminal structure as general chip parts it has excellent mounting stability characteristics and can also be mounted to general-purpose land patterns. By using a closed magnetic circuit structure leakage flux is minimized. The rated voltage of 40V is realized by design that emphasizes voltage resistance. Operating temperature range: 55 to +150C (including self-temperature rise) Compliant with AEC-Q200 APPLICATION For automotive (headlights, electronic power steering, meter cluster, ADAS ECU, other) Application guides: Automotive (xEV), Car Infotainment PART NUMBER CONSTRUCTION TFM 252012 ALV A 4R7 M T AA LWH dimensions Inductance Characteristic Automotive Inductance Series name Packaging style Internal code 2.52.01.2 mm type use (H) tolerance CHARACTERISTICS SPECIFICATION TABLE L DC resistance Rated current Rated voltage Part No. Isat Itemp (H) Tolerance (m )max.
