Fixed Inductors
4922R-31H Application Field and Working Principle
Fixed inductors refer to inductors that are exposed to a magnetic field to generate a magnetic flux. This flux in turn induces a voltage that does not change with frequency. The 4922R-31H is a fixed inductor that is most commonly used in frequency division applications and specializes in low-power applications. It can also be used in DC/DC converters, switching regulators, and voltage converters.The 4922R-31H has an inductance of 4.9, 22 ohms, and has a rated current of 1.1A. It operates at a temperature range from -40 °C to 115 °C. It has a pin size of 5.85mm x 5.85mm and is RoHS compliant. Its construction includes a ferrite core and winding. The ferrite core gives it low resistance and the winding allows it to generate a voltage.The working principle of the 4922R-31H is quite simple. The device receives an AC power signal and converts it into a DC voltage of a specified value. This is done by creating a magnetic field. Once the AC signal is applied, a current is induced in the winding of the inductor which generates a magnetic field. The magnetic field will vary in strength depending on the amplitude of the AC signal. This varying magnetic field will then induce a voltage in the winding of the resistor. The voltage created is proportional to the strength of the magnetic field and is also inversely proportional to the frequency of the AC signal.The 4922R-31H can be used in many applications. For example, it can be used in frequency division applications for signal conditioning. It can also be used in DC/DC converters for power stabilizers. In addition, it is used in switching regulators, making them capable of maintaining a steady voltage. It can also be used in voltage converters, which are used to convert one voltage level to another.In conclusion, the 4922R-31H is a useful fixed inductor with applications in frequency division, DC/DC converters, switching regulators, and voltage converters. Its construction is simple and its working principle is easy to understand. It is an effective device for low power applications due to its ability to induce a voltage proportional to the strength of the magnetic field, and its low resistance due to the ferrite core.The specific data is subject to PDF, and the above content is for reference
