SMD power inductor LanTu Micro SNR5040-220MT featuring magnetic resin shield and closed magnetic circuit
Product Overview
The SNR5040 Series Magnetic Resin Shielded SMD Power Inductors are automatic assembly constructed power inductors featuring magnetic resin shielding to significantly reduce buzz noise to ultra-low levels. They offer large current handling capability with low DCR, and metallized electrodes on the ferrite core ensure excellent shock resistance and durability. The closed magnetic circuit design minimizes leakage flux and enhances EMI resistance, while the compact size saves PCB space and power. These inductors are widely used in applications such as LED backlights, flat-screen TVs, set-top boxes, notebooks, desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, multimedia devices, automotive products, telecommunication equipment, and DC-DC converters. They comply with RoHS, Halogen Free, and REACH standards.
