The inductor is generally composed of a skeleton, a winding, a shield, a package material, a magnetic core, or an iron core.
1, Skeleton Skeleton Skeleton refers to the coiled stent. Some large-sized fixed inductors or adjustable inductors (such as oscillation coils, choke coils, etc.), most of which enclose the enameled wire (or yarn wrapped wire) around the skeleton, and then the magnetic core or copper core, iron core, etc. Load the inner cavity of the skeleton to increase its inductance. Skeletons are usually made of plastics, bakelite, and ceramics, and can be made into different shapes according to actual needs. Small inductors, such as color code inductors, typically do not use a bobbin, but instead directly wrap the magnet wire around the core. Hollow inductors (also called tire-out coils or air-core coils, which are mostly used in high-frequency circuits) do not use cores, frames, shields, etc., but first take off the mold and then take off the mold, and pull the coil between the circle A certain distance.
2. Winding Winding refers to a set of coils with a specified function, which is the basic component of the inductor. The windings are divided into single layers and multiple layers. The single-layer winding has two types of tight winding (when the wire is wound by one turn and one winding around) and the inter-winding (when the winding is wound, each wire is separated by a certain distance); the multilayer winding has layered flat winding and chaos. Around, beehive-style and other methods.
3, magnetic core and magnetic rod core and magnetic rod generally use nickel-zinc ferrite (NX series) or manganese zinc ferrite (MX series) and other materials, it has "work" shape, column, hat, "E" Shapes, pots and other shapes.
4, iron core material mainly silicon steel, permalloy, etc., its shape is mostly "E" type.
5. Shielding cover In order to prevent the magnetic field generated by some inductors during operation from affecting the normal operation of other circuits and components, a metal screen cover (such as the oscillation coil of a semiconductor radio, etc.) has been added. Shielded inductors increase coil losses and reduce Q.
6, the packaging material Some inductors (such as color code inductors, color ring inductors, etc.) after winding, with the packaging material to seal the coil and the core. The packaging material is plastic or epoxy resin.
