What types of chip inductors can be divided into
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.
Low-power winding inductors are made by winding enameled wires on the frame. Low-power multilayer (stacked) inductors are non-winding inductors made of magnetic materials and multilayer technology. Generally, ferrite paste and conductive paste are alternately laminated and sintered into a whole, with a closed magnetic circuit, so Has a magnetic shielding effect.
High-power chip winding inductors are made of square or round I-shaped ferrite as the skeleton, wound with enameled wire, and the working frequency can reach 200khz.
The main parameters of chip inductors include size, inductance, allowable error, q value, allowable current and oscillation frequency, etc. The main parameters of chip high-power inductors are the maximum current and operating frequency.
