Product Description
The ring iron core used for switching power supply is made of nano-crystalline alloy, which has a high permeability and low loss and is an ideal material used to make the main transformers, magnetic amplifier, choke circle, energy storage inductors, filter inductors, common mode inductance, the peak suppressor in single-ended, and push-pull or full-bridge high frequency switching power supply as well.
Features:
1. High saturation magnetic flux density can effectively reduce the size of the transformer.
2. High permeability and low coercivity can improve the efficiency of the transformer and reduce the magnetizing power and distribution parameters of the coil.
3. Featuring with low loss and low magnetostriction coefficient.
