Product Overview
The SNR8040 Series Magnetic Resin Shielded SMD Power Inductors are automatic assembly compatible components designed for high-performance applications. Featuring a magnetic-resin shielded construction, they significantly reduce buzz noise to ultra-low levels. These inductors offer large current handling capabilities with low DC resistance, a closed magnetic circuit design for reduced leakage flux and enhanced EMI resistance, and metallization on the ferrite core for excellent shock resistance and durability. Their compact size saves PCB real estate and reduces power consumption. They are widely used in LED backlights, flat-screen TVs, set-top boxes, notebooks, desktop computers, servers, graphic cards, portable gaming devices, personal navigation systems, multimedia devices, automotive products, and telecommunication base stations, as well as DC-DC converters.
