1. İskelet İskelet genellikle bobini sarmak için braketi ifade eder. Bazı daha büyük sabit indüktörler or adjustable indüktörler (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 indüktörler (such as color-coded indüktörler) generally do not use a bobbin, but instead have the enameled wire wound directly around the core. Air-core indüktörler (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 indüktörler. 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. Manyetik çekirdek ve manyetik çubuk Manyetik çekirdek ve manyetik çubuk genellikle nikel-çinko ferrit (NX serisi) veya manganez-çinko ferrit (MX serisi) ve "I" şekline, sütun şekline, şapka şekline sahip diğer malzemelerden yapılır. , "E" Şekli, şekil ve diğer şekiller verebilir.

4. Demir çekirdek Demir çekirdek malzemesi esas olarak silikon çelik sac, permalloy vb. Içerir ve şekli çoğunlukla "E" tipindedir.

5. Shielding cover In order to prevent the magnetic field generated by some indüktörler 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 indüktörler will increase the loss of the coil and reduce the Q value.

6. Packaging materials After some indüktörler (such as color code indüktörler, color ring indüktörler, etc.) are wound, the coils and magnetic cores are sealed with packaging materials. The encapsulation material is plastic or epoxy resin.
