Introduction to PD73R-823K Fixed Inductors

Fixed inductors, like the PD73R-823K, are components specifically designed to store energy in the form of magnetic fields. They are made up of conductive loops of wires, and any type of material that is capable of carrying an electric current. This article will explore the application field and working principle of the PD73R-823K.

Application Field

The PD73R-823K fixed inductor is primarily used in the field of radio-frequency identification, or RFID. This type of technology is used to communicate with devices, allowing them to be activated or adjusted from a distance. It is most commonly used in credit cards, access control systems, and automatic toll systems. This type of inductor is also used in filter circuitry, motor control, and inductance switching circuits.

Working Principle

The PD73R-823K works on the principle of electromagnetic induction. When alternating current passes through the loop of wire inside the inductor, it creates a magnetic field. This magnetic field induces a current in the loop, which is then stored as energy in the inductor. When the alternating current is removed, the stored energy is released in the form of a current.The PD73R-823K is designed to have high inductance, which means that it can store more energy than smaller inductors. This type of inductor also has low resistance, allowing for more efficient energy storage.

Conclusion

The PD73R-823K is a type of fixed inductor designed for the field of RFID. Its working principle is based on the principle of electromagnetic induction, whereby alternating current passing through the inductor creates a magnetic field that induces and stores energy. The PD73R-823K has high inductance and low resistance, allowing it to store more energy efficiently.
