Applications of Air Core Coils 

Introduction

Air core coils  are essential electromagnetic components that eliminate core losses, making them ideal for high-frequency, high-efficiency, and low-distortion applications. Unlike ferrite or iron-core coils, they rely solely on the winding structure to generate inductance, offering superior thermal stability and linearity.

Golden Eagle specializes in manufacturing precision air core coils from 1mm to 300mm, serving industries such as RF communications, medical devices, aerospace, and automotive electronics.
