INDUCTORS Inductors for power circuits Cl Pb Br Thin-film metal magnetic material REACH Halogen Lead RoHS SVHC-Free Free Free TFM-ALD series TFM201208ALD 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. APPLICATION Smart phones, tablet terminals, HDDs, SSDs, DVCs, DSCs, mobile display panels, portable game devices, compact power supply modules, other Application guides: Smart phones/tablets PART NUMBER CONSTRUCTION TFM 201208 ALD - 1R0 M T CA LWH dimensions Inductance Characteristic Inductance Series name Packaging style Internal code type tolerance 2.01.250.8 mm (H) CHARACTERISTICS SPECIFICATION TABLE L L measuring DC resistance Rated current Part No. frequency Isat Itemp (H) Tolerance (MHz) (m )max.
