Ring high frequency power transformer magnetic core

Introduction

Characteristics

1. High saturation magnetic induction intensity --effectively reducing transformer volume; 2. High magnetic conductivity and low coercivity --improve transformer efficiency, reduce excitation power and iron loss; 3. Low loss -- reduce temperature rise; 4. High temperature stability--can work in the range of-55℃-130℃ for a long time.
