The SNR8040 Series Magnetic Resin Shielded SMD Power Inductors from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are automatic assembly constructed power inductors featuring magnetic resin shielding to significantly reduce buzz noise to ultra-low levels. They offer large current handling capabilities with low DC resistance, excellent shock resistance due to metallization on the ferrite core, and a closed magnetic circuit design that minimizes leakage flux and enhances EMI resistance. These space-saving and power-efficient components are widely used in applications such as LED backlights, flat-screen TVs, set-top boxes, notebooks, servers, graphic cards, portable gaming devices, personal navigation systems, multimedia devices, automotive systems, telecommunication base stations, and DC-DC converters. They comply with RoHS, Halogen Free, and REACH standards.
