Introduction to Coil Inductor
A coil inductor, also known as an inductor or reactor, is a passive two - terminal electrical component that stores energy in a magnetic field when electric current flows through it. It consists of a coil of wire, usually wound around a core made of a magnetic material such as iron, ferrite, or air. The basic principle behind an inductor is Faraday's law of electromagnetic induction. When the current through the inductor changes, it induces an electromotive force (EMF) that opposes the change in current.
Coil inductors are widely used in various electronic circuits, including power supplies, filters, oscillators, and radio frequency (RF) circuits. In power supplies, they are used to smooth out the DC output by reducing the ripple voltage. In filters, inductors can be used in combination with capacitors to form low - pass, high - pass, or band - pass filters. In RF circuits, they are used for impedance matching and tuning.
Now, let's take a look at the top 10 coil inductor factories in China in 2025.
