SMD Unshielded Power Inductors – SM4520
We are offering 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. A fully automated winding/soldering/testing and packing machine produces this miniature wire wound SMD power inductor. 100% check before each shipment, the testing included the characteristic inductance value, DC resistance, Isat current and layer isolation.
Minimum order quantity: 1 piece
Supply capacity: 1,000,000 pieces per month
