2026 Top 10 Hollow Coil Manufacturers in China - Blog

Introduction to Hollow Coil

A hollow coil, also known as an air - core coil, is a type of inductor that does not have a magnetic core made of ferromagnetic material. Instead, it uses air as the core medium. Hollow coils are widely used in various electronic applications due to their unique properties. They offer low inductance values with high Q - factors, which means they have less energy loss and better performance in high - frequency circuits. Their self - resonance frequency is relatively high, making them suitable for applications such as radio frequency (RF) circuits, wireless communication devices, and high - frequency transformers.
