Fixed Inductors
A fixed inductor is a passive electronic part that can convert electrical energy to magnetism for storage. It is also called a "coil," because normally the wire is wrapped around the core in a coil shape. This part works by making the current flow to the coil section to generate a magnetic field. The more winding that the wire has, the stronger the magnetic field. Fixed inductors are classified into types according to usage applications such as high-frequency circuits or power supply circuits; according to core types such as air-core or core system; or according to shapes such as lead type or SMD type (surface mount type). Three structure types are also available for the SMD type: wound types, multilayer types and thin-film types. The particular characteristics of each are used for application in electronic equipment in a wide range of fields, including radio and television, as well as wireless applications, mobile phones, satellite communications and weather radar.
