Product Description
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 reduce buzz noise to ultra-low levels, offer large current handling with low DC resistance, and provide excellent shock resistance due to metallization on the ferrite core. The closed magnetic circuit design minimizes leakage flux and EMI, making them space-saving and power-efficient. These inductors are RoHS, Halogen Free, and REACH compliant.
Features
- Magnetic-resin shielded construction reduces buzz noise to ultra-low levels.
- Large Current and Low DCR.
- Metallization on Ferrite Core results in excellent shock resistance and damage-free durability.
- Closed magnetic circuit design reduces leakage flux and Electro Magnetic Interference (EMI).
- Takes up less PCB real estate and saves more power.
- Small parasitic capacitance.
- RoHS, Halogen Free and REACH Compliance.
Applications
- LED backlight
- Flat-screen TVs
