Low Power Switch Transformer Core

Low Power Switch Transformer Core
Product Description
Amorphous alloy produced by switching power supply toroidal cores with high permeability and low loss, is applied to single-ended, push-pull or full-bridge high frequency switching power supply of the main transformers, magnetic amplifiers, chokes, energy storage inductors, filter inductors, common mode inductors and an ideal material for the peak suppressor. 
Performance characteristic: 
1. High saturation magnetic induction can effectively reduce the size of the transformer. 
2. High permeability, low coercive force can improve the efficiency of transformer, coil distribution of power and reduce the excitation parameters. 
3. Low loss, low magnetostriction coefficient.
