Chip inductors can be divided into low-power inductors and high-power inductors. Chip inductors, low-power inductors are mainly used in frequency selective circuits and oscillating circuits; high-power inductors are mainly used in dc/dc converters, used as energy storage components or lc filtering. There are three types of low-power inductors: wire-wound, multilayer, and high-frequency; high-power inductors are all wire-wound.
