FDSD/0512/0515/0518 Series metal alloy inductors incorporate a magnetic iron powder that allows capability for a large current. These SMD fixed inductors are reflow solderable and have a low audible noise. These SMD inductors are 5.2. X 4.0 mm square and 1.2/1.5/1.8. mm max. height. These metal alloy inductors use flat wire for low DC resistance. FDSD series inductors are ideal for DC-DC Convertor applications, are halogen free and RoHS compliant.
