Power Inductor/SMD Inductor

Power inductors, also known as chip inductors, high current inductors and surface mount high power inductors(SMD inductors). It has the characteristics of miniaturization, high quality, high energy storage and low resistance.

Generally, the inductors in electronic circuits are air-core coils or coils with magnetic cores, which can only pass small currents and withstand low voltages; while power inductors also have air-core coils and some with magnetic cores. Their main features are: The thick wire is wound and can withstand tens of amps, hundreds, thousands, or even tens of thousands of amps.

Power chip inductors are divided into two types: with magnetic cover and without magnetic cover. They are mainly composed of magnetic core and copper wire. It mainly plays the role of filtering and oscillation in the circuit.

The purpose of power inductors is to reduce core losses in an application that requires voltage conversion. This electronic component can also be used in a magnetic field created by a tightly wound coil to receive or store energy, reduce signal loss in a system design and filter EMI noise.
