Product Description
Magnetic Resin Shielded SMD Power Inductors - SMNR Series
The SMNR series are automatic assembly constructed power inductors, shielded with magnetic resin. This construction significantly reduces buzz noise to ultra-low levels. They feature large current handling, low DC resistance, and metallization on the ferrite core for excellent shock resistance and durability. The closed magnetic circuit design minimizes leakage flux and electromagnetic interference (EMI), making them space-saving and power-efficient with small parasitic capacitance. These inductors are RoHS, Halogen Free, and REACH compliant.
Features
