Fixed inductors are passive components which are widely used in electrical circuits to store energy in the form of magnetic fields. These components are generally composed of a coil wound with metal wire and housed in an insulator. The core material used in the center of the coil depends on the characteristics of the inductor.

The 9220-22-RC is one of the most widely used fixed inductors on the market and is primarily used in high frequency applications. It is specifically designed for use in RF and VHF applications such as switching power supplies, telecommunications equipment, and high-end consumer audio and video electronics. This type of inductor is a non-polarized, two-pin device, meaning that it can be used with either positive or negative leads.

The inductance of the 9220-22-RC is rated at 4.2 mH with a current rating of 1.7 A and a DC resistance of 190 mOhms. The inductor also features a radial design which minimizes parasitic oscillations in radio-frequency applications. The high frequency performance of this inductor and its stability over temperature make it an ideal choice for many applications.

The working principle of a fixed inductor is that when a direct current is introduced through the coil, a magnetic field is generated. This field stores energy and causes a voltage to be generated across the coil when the current is removed. This voltage is known as inductance and is proportional to the amount of current flowing through the device. The inductance of the 9220-22-RC is 4.2 mH, meaning that it produces a voltage of 4.2 mV at a rate of 1.7 A.

Fixed inductors can also be used to create tuneable LC circuits. These circuits are made by combining a fixed inductor with a variable capacitor. This type of circuit is used for a variety of applications, such as radio receivers, frequency synthesizers, and signal processing applications. The inductor in the circuit acts to tune the circuit to a specific frequency while the capacitor is used to control the amount of current in the circuit.

Overall, the 9220-22-RC is a versatile fixed inductor which is well-suited for high-frequency applications. Its radial design minimizes parasitic oscillations and its ability to store energy in its military field makes it an ideal choice for many applications. The working principle of this type of inductor is that when a DC current is introduced, a magnetic field is generated and stored energy which is then released as a voltage in the form of inductance.
