Product Details

Introduction

This shape is developed to get higher DCB characteristics when E types of ferrite cores are proper with higher current.

Features

Because plastic bobbins are used with E shape, higher productivity are available. Also good temperature stability and large energy storage capacity are available.

Applications

Multiple circuit choke coil and output chokes for SMPS. Also used for flyback transformed.
