Working Principle of DR73-820-R Fixed Inductor

The DR73-820-R fixed inductor works on the principle of Faraday’s Law of Electromagnetic Induction. In this law, an electric current is induced when a magnetic field is changed by either increasing or decreasing its strength. The DR73-820-R consists of two rectangular steel plates with a gap between them. These plates act as the magnetic field. When a voltage is applied to the plates, the flux generated through the plates produces a magnetic field, which induces a current through the inductor. This induced current will then be able to perform various functions based on its circuit application.

Conclusion

The DR73-820-R is a type of fixed inductor that has many applications, including EMI/RFI filters, DC-DC converters, switching power supplies, high-frequency converters, signal processing circuits, and DC-DC step-up/down voltage controllers. It works on the principle of Faraday’s Law of Electromagnetic Induction by generating a magnetic field to induce a current when a voltage is applied to the plates. The DR73-820-R is a highly versatile inductor with many different applications.
