INDUCTORS Inductors for power circuits Cl Pb Br Thin-film metal magnetic material REACH Halogen Lead RoHS SVHC-Free Free Free TFM-ALMA series (for automotive) AEC-Q200 TFM252012ALMA 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. Compliant with AEC-Q200 APPLICATION ADAS ECU, in-Vehicle camera (view camera, sensing camera), radar, meter cluster, automotive communication module Other power supply circuit uses Application guides: Automotive (xEV), Car Infotainment PART NUMBER CONSTRUCTION TFM 252012 ALM A 1R0 M T AA LWH dimensions Characteristic Automotive Inductance Inductance Series name Packaging style Internal code 2.52.01.2 mm type use (H) tolerance CHARACTERISTICS SPECIFICATION TABLE L L measuring DC resistance Rated Part No. Rated current frequency voltage Isat Itemp (H) Tolerance (MHz) (m )max.
