Surface Mount Shielded Coil Inductors – SMR74B
Our SMR series wire wound shielded SMD power inductors feature a silver plated ferrite drum core that provides excellent efficiency, high power density, and excellent leakage flux isolation. Magnetic radiated emissions are relatively low due to the toroidal core shielding structure. Utilizing a copper/tin base, once soldered to the PCB board, it provides a rugged structure that can withstand shock and vibration environments.
Minimum order quantity: 1 piece
Supply capacity: 1,000,000 pieces per month
