Description

Introduction

The most optomized shape to make magnetic field. No leakage inductance and other lossss are available. Each particle is insulated so no needed to gapping like ferrite cores.

 

Features

Shape is like a donut and directly wound normally. This shape gets full of the characteristics of material which applied. Good DCB characteristics are shown.

 

Applications

They are applied to line filter ande inductors.
