The SNR8040 Series Magnetic Resin Shielded SMD Power Inductors are automatic assembly compatible power inductors designed for high-performance applications. Featuring a magnetic-resin shielded construction, these inductors significantly reduce buzz noise to ultra-low levels. They offer large current handling capabilities with low DC resistance, a closed magnetic circuit design for reduced leakage flux and strong EMI resistance, and metallization on the ferrite core for excellent shock resistance and durability. These space-saving and power-efficient components are suitable for a wide range of applications including 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.
