Air Core Inductors for Supporting High Frequency Applications

Air Core Inductor

Air core inductors are non-magnetic core inductors. Also known as air core coils. The coils can be wound on forms made from resinite or plastic or they can be built as self supporting coils using bondable magnet wire. Air core inductors are mainly used in applications with high frequencies and low inductance requirements. Custom Coils designs and manufactures air core inductors for different types of industrial and commercial applications.

Air Core Inductor Offerings

At Custom Coils we design our air core inductors to meet our customer’s size and inductance requirements. There are a few advantages of not having a magnetic core. One is the inductance value is very stable over frequency and temperature ranges. Since the core is a nonmagnetic material, the permeability values do not increase over temperature. The greatest advantage of the air core coil design is that it does not suffer from energy losses like an inductor built with ferromagnetic cores.

We can design our air core coils in a variety of lengths, shapes, and sizes. Customers can see our range of dimensions in the list below.

  • Length up to 4”
  • Outer Diameter up to 8”
  • Inner Diameter up to 3/32”
  • Wire size range from 12 to 36 AWG
