Product Overview
The SNR8040 Series are automatic assembly constructed, magnetic resin shielded SMD power inductors designed to minimize buzz noise to ultra-low levels. They feature a closed magnetic circuit design for reduced leakage flux and strong EMI resistance, offering large current handling capabilities with low DC resistance. These space-saving and power-efficient inductors are suitable for a wide range of applications including LED backlights, flat-screen TVs, notebooks, servers, graphics cards, automotive systems, and DC-DC converters. They are constructed with metallization on the ferrite core for excellent shock resistance and durability, and comply with RoHS, Halogen Free, and REACH standards.
