1. Esqueleto El esqueleto generalmente se refiere al soporte para enrollar la bobina. Algunos fijos más grandes inductores or adjustable inductores (such as oscillating coils, choke coils, etc.), most of which are enameled wire (or yarn-covered wire) around the skeleton, and then the magnetic core or copper core, iron core, etc. Installed into the inner cavity of the skeleton to increase its inductance. The skeleton is usually made of plastic, bakelite, and ceramics, and can be made into different shapes according to actual needs. Small inductores (such as color-coded inductores) generally do not use a bobbin, but instead have the enameled wire wound directly around the core. Air-core inductores (also known as unwrapped coils or air-core coils, mostly used in high-frequency circuits) do not use magnetic cores, skeletons and shields, etc., but are first wound on the mold and then take off the mold, and the coil is pulled between each coil. Drive a certain distance.
2. Winding Winding refers to a group of coils with specified functions, which is the basic component of inductores. There are single-layer and multi-layer windings. There are two types of single-layer windings: dense winding (conductors are wound one turn after another) and intermediate winding (there is a certain distance between each turn of wires during winding); multi-layer windings have layered flat winding, random winding Winding, honeycomb winding, etc.
3. Núcleo magnético y varilla magnética El núcleo magnético y la varilla magnética generalmente están hechos de ferrita de níquel-zinc (serie NX) o ferrita de manganeso-zinc (serie MX) y otros materiales, que tienen forma de "I", forma de columna, forma de sombrero , Forma "E", forma de lata y otras formas.
4. Núcleo de hierro El material del núcleo de hierro incluye principalmente láminas de acero al silicio, permalloy, etc., y su forma es principalmente de tipo "E".
5. Shielding cover In order to prevent the magnetic field generated by some inductores from affecting the normal operation of other circuits and components, a metal screen cover (such as the oscillation coil of a semiconductor radio, etc.) is added to it. The use of shielded inductores will increase the loss of the coil and reduce the Q value.
6. Packaging materials After some inductores (such as color code inductores, color ring inductores, etc.) are wound, the coils and magnetic cores are sealed with packaging materials. The encapsulation material is plastic or epoxy resin.
