Fixed inductors are also known as inductive coils, chokes, reactors, and delayers. They are most commonly used in ac/dc converters, rectifiers, inverters, and motor controls. Inductors are used to store electrical energy in the form of a magnetic field. They are made of ferromagnetic materials such as iron and steel, and are embedded in a housing that is either air- or liquid-filled. 4922-18H is one of the popular fixed inductors in the market.

The 4922-18H fixed inductor is a 22mH (millihenry) unshielded inductor with a saturation current of 20 Amps and a resistance of 0.044 ohms. It is designed to dissipate heat and is equipped with a large ferrite core, which enables it to operate at higher frequencies. It has a rated ripple current of 40 Amps and an inductance of 18mH (millihenry).

The 4922-18H inductor is widely used in many applications due to its ability to provide a consistent current and voltage. Its high frequency capabilities and low resistance make it suitable for switching power supplies, LED lighting, power factor correction, and over-current protection. In addition, because of its high frequency performance, the 4922-18H is a good choice for high-power applications such as DC motors.

The working principle of 4922-18H fixed inductor involves the passage of alternating current (AC) through the inductor, creating a magnetic field which in turn creates a voltage drop across the inductor. The voltage drop is proportional to the amount of current, and the amount of current is proportional to the amount of inductance. This voltage is then used to power the device or circuit, depending on the application.

In conclusion, the 4922-18H is a popular and reliable fixed inductor. Its high frequency operation and low resistance make it ideal for a variety of applications, including switching power supplies, over-current protection, and LED lighting. Its working principle involves the passage of AC through the inductor, creating a magnetic field which in turn creates a voltage drop that powers the device or circuit.
