The SNR4018 Series is an automatic assembly compatible, magnetic resin shielded SMD power inductor designed to minimize buzz noise to ultra-low levels. It features a closed magnetic circuit design for reduced leakage flux and strong EMI resistance, along with metallization on the ferrite core for excellent shock resistance and durability. This series offers high current capability and low DC resistance, making it space-saving and power-efficient. It is widely used in applications such as LED backlights, flat-screen TVs, notebooks, servers, graphic cards, automotive products, and DC-DC converters. The inductors comply with RoHS, Halogen Free, and REACH standards.
