Magnetic Resin Shielded SMD Power Inductors - SMNR Series
The SMNR series are automatic assembly constructed power inductors shielded with magnetic resin. They are designed to significantly reduce buzz noise to ultra-low levels, offer large current handling capabilities with low DC resistance, and are built for durability with metallization on the ferrite core for excellent shock resistance. The closed magnetic circuit design minimizes flux leakage and enhances EMI resistance, while their compact size saves PCB space and power. These inductors comply with RoHS, Halogen Free, and REACH standards.
