The SNR4030 Series is an automatic assembly constructed, magnetic resin shielded SMD power inductor designed to significantly reduce buzz noise to ultra-low levels. It features a closed magnetic circuit design, minimizing leakage flux and enhancing Electro Magnetic Interference (EMI) resistance. This series offers large current handling capability with low DCR, metallized ferrite core electrodes for excellent shock resistance and durability, and a space-saving, power-efficient design. It is widely applied in LED backlights, flat-screen TVs, notebooks, servers, graphic cards, automotive systems, and DC-DC converters. The product complies with RoHS, Halogen Free, and REACH standards.
