Product Description

EI Series Step up down ferrite core high Frequency EI Transformer
Features

1) Specially used in switching power supply and kinds of high-frequency circuit;
2) Plays a role in oscillating and separating; 
3) Small volume, light weight and nice appearance.
4) Possessing of high permeability, high saturation flux density and low loss.
    Especially about at 100°C the power loss goes bottom.
