SMD Unshielded Power Inductor – SM7850
We offer a wide range of power inductors in many different sizes and shapes, surface mounts used in switching mode power supplies, DC-DC converters, and EMI filtering applications. This miniature wire-wound SMD power inductor is produced by a fully automated winding/soldering/testing and packing machine. Before each shipment, it is 100% checked, and the testing includes the characteristic inductance value, DC resistance, Isat current, and layer isolation.
Minimum order quantity: 1 piece
Supply capacity: 1,000,000 pieces per month
