1. Skelett Als Skelett bezeichnet man im Allgemeinen die Halterung zum Wickeln der Spule. Einige größere fest Induktoren or adjustable Induktoren (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 Induktoren (such as color-coded Induktoren) generally do not use a bobbin, but instead have the enameled wire wound directly around the core. Air-core Induktoren (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 Induktoren. 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. Magnetkern und Magnetstab Der Magnetkern und der Magnetstab bestehen im Allgemeinen aus Nickel-Zink-Ferrit (NX-Serie) oder Mangan-Zink-Ferrit (MX-Serie) und anderen Materialien, die eine „I“-Form, eine Säulenform oder eine Hutform haben , "E"-Form, Dosenform und andere Formen.

4. Eisenkern Das Material des Eisenkerns umfasst hauptsächlich Siliziumstahlblech, Permalloy usw., und seine Form ist meistens vom Typ „E“.

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

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