EF25 Pulse High Frequency Transformer | Pure Copper Winding, Ferrite Core & Thickened Insulated Wire

2026-08-11

1. Introduction

Our EF25 pulse high frequency transformer features pure copper winding, ferrite core and thickened insulated wire. Ideal for switching power supply, charger and consumer electronics. Get custom service now. Stable power conversion is essential for compact switching power supply designs. Many engineers encounter overheating, insulation failure and low efficiency when using inferior transformers. Our EF25 pulse high frequency transformer solves these common pain points. Built with pure copper winding, high-performance ferrite core and thickened insulated wire, it delivers reliable performance for pulse and high-frequency power supply applications.

2. Core Advantages of EF25 Pulse High Frequency Transformer

1. 100% Pure Copper Winding

The coil adopts oxygen-free pure copper wire with low resistivity. Compared with copper-clad aluminum alternatives, it cuts heat loss during continuous operation, maintains stable efficiency under pulse load, and extends service life of your equipment.

2. High-Quality Ferrite Core

Equipped with manganese-zinc ferrite core, it owns low high-frequency loss and high magnetic permeability. The optimized EF shape structure reduces magnetic leakage, supports wide working frequency and guarantees efficient energy transmission.

3. Thickened Insulated Wire

We use thickened high-temperature insulation coating on windings. It boosts dielectric strength, prevents insulation breakdown under long-time operation, improves safety performance and adapts to complicated working environments.

3. Typical Applications

  • Switching power supplies
  • Battery chargers
  • LED drive power units
  • Small household electronic equipment
  • Industrial control auxiliary power supply

Custom Support

Standard EF25 transformers are available in stock. We support customized winding turns, pin layout, inductance parameters and insulation requirements. All products comply with RoHS standards.
