Horizontal Ferrite Core EE27 High Efficiency Industrial Power Supply PFC Inductor

Short Description:

SH-P27 is a PFC inductor used in industrial power supplies. It replaces the low-efficiency and expensive magnetic winding structure with the high-efficiency EE structure. At the same time, by adopting a new magnetic core design scheme, the problems of high loss in the air gap and unsatisfactory electromagnetic compatibility effect of the traditional EE core are solved.

Introduction

This product is mainly used in the primary input part of 180W industrial power supply circuit, and improves the working efficiency of the circuit through power factor correction. In order to obtain better characteristics, the traditional solution mostly uses a magnetic ring structure, but this product uses a composite core and uses an EE structure to achieve electrical characteristics comparable to the magnetic ring structure.
