TFM322512ALMA4R7MTAA

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 TFM322512ALMA 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 PART NUMBER CONSTRUCTION TFM 322512 ALM A 1R0 M T AA LWH dimensions Inductance Characteristic Automotive Inductance Series name Packaging style Internal code type use tolerance 3.22.51.2 mm (H) CHARACTERISTICS SPECIFICATION TABLE L L measuring DC resistance Rated current Rated Part No. frequency voltage Isat Itemp (H) Tolerance (MHz) (m )max.
