Best 10 Hollow Coil Manufacturers in China 2025 - 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 consists of a wire wound around a hollow form, such as a plastic or ceramic tube. Hollow coils are widely used in various electronic applications due to their unique electrical properties.

One of the main advantages of hollow coils is their low inductance variation with temperature and magnetic field. They also have relatively low self - capacitance, which makes them suitable for high - frequency applications. Hollow coils are commonly used in radio frequency (RF) circuits, such as antennas, oscillators, and filters. They are also used in some power electronics applications, such as wireless charging systems and high - frequency power supplies.

In China, there are many manufacturers that produce high - quality hollow coils. Here are the top 10 hollow coil manufacturers in China in 2025:
