Fixed inductors are electrical components which provide inductance and typically have a large fixed inductance. It is composed of an inductor wound around a core of iron or other magnetic material and connected to two terminals. Fixed inductors come in a wide variety of shapes and sizes, from the tiny components used in electronics, to the large chokes used in power circuits.

2221-H-RC is a special type of fixed inductor which can be applied to both high frequency and high efficiency power. This kind of inductor has a hollow silk sleeve which is filled with a strong resin buffer that provides a great insulation. The insulated contact core is wound with superior enameled copper wire to effectively lower the winding resistance and the mechanical vibration loss. The coil is wrapped by an iron-based magnetic core which enhances the inductor\'s capability to reduce noise and enlarge output current.

The application field of 2221-H-RC covers high frequency circuits, high speed switching, high power supplies, and high efficient exchangers. Due to its high efficiency power feature, 2221-H-RC can be widely used in charger, adapters, rectifiers, electric system and so on. Moreover, it can also work as an amplifier in audio equipment.

The working principle of 2221-H-RC is based on the law of electromagnetic induction. The winding of copper wire produces an electromotive force when the core is subject to a change of magnetic induction.The electromotive force resulting from the winding of copper wire generates a counter-electromagnetic force which is opposite to the induced electromotive force. In this way, the inductors can store energy temporarily and deliver energy back to the circuit. Furthermore, the winding shape and magnetic material in the core affect the magnitude of the inductive reactance.

2221-H-RC is widely used in various applications as a fixed inductor because of its high frequency, high efficiency and good insulation property. Its working principle is based on the law of electromagnetic induction and it can offer reliable performance when used in high frequency circuits, high speed switching, and high power supplies.
