Color-coded inductors use colored bands to indicate their inductance value. They’re commonly used in filtering and resonant circuits to improve signal quality and stability.

Structurally, they’re made by winding enameled wire around a magnetic core, with a protective resin coating on the outside. This makes them highly durable and long-lasting—perfect for use in all kinds of electronic devices.

A wire-wound inductor is a common type of inductor made by winding insulated wire around a magnetic or non-magnetic core. It plays a key role in electronic circuits by storing energy, filtering signals, and limiting current.

Thanks to their high inductance, low DC resistance (DCR), and strong frequency performance, wire-wound inductors are widely used in power supplies, RF circuits, and signal processing applications.
