Hollow inductance coil

1. (also known as bead breaking coil or hollow coil, which is mostly used in high frequency circuit) instead of using magnetic core, framework and shielding cover, the mould is first wound on the mould and then taken off, and the coils are pulled apart for a certain distance.

2. Winding refers to a group of coils with specified functions, which is the basic component of I-inductance.

The winding is divided into single layer and multi-layer. There are two kinds of single-layer winding: close winding (wires are wound one by one) and inter winding (wires are separated by a certain distance in each winding). There are many kinds of multi-layer winding, such as flat winding, random winding, honeycomb winding, etc.

3. The core and bar are generally made of nickel zinc ferrite (NX Series) or manganese zinc ferrite (MX Series), which has various shapes such as "I" shape, column shape, cap shape, "e" shape, can shape and ring shape.

4. The core material mainly includes silicon steel sheet and permalloy, and its shape is mostly "e" type.

5. In order to avoid the magnetic field produced by some inductive coils affecting the normal operation of other circuits and components, a metal screen cover (such as the oscillating coil of semiconductor radio) is added to the shield cover. The inductor with shield will increase the loss of coil and reduce the Q value.
