Fixed Inductors are electrical components used in circuits to store and control the flux of electrical current. They can be used to regulate the delivery of power to circuits or components. The DRA124-820-R is a type of fixed inductor used primarily in high-voltage AC power applications.

The DRA124-820-R is a self-supporting high voltage inductor with a ferrite core. It has a 12V coil winding resistance of 0.18 ohms and an inductance of 820uH. This inductor is capable of handling peak currents of up to 270A and is capable of withstanding voltages up to 2000V AC.

The DRA124-820-R is typically used in power supplies, DC-DC conversion applications and AC motor speed control. It is also suitable for use in high-voltage AC circuits where voltage spikes can occur.

The working principle of the DRA124-820-R is based on Faraday’s Law of Induction. When an alternating current or AC voltage is applied to the inductor, a varying magnetic field is generated around the inductor. This varying magnetic field induces an electric current in the inductor, thereby storing energy in the form of a magnetic field around the inductor.

When a voltage spike occurs in the AC circuit, the stored magnetic field around the inductor collapses. As the magnetic field collapses, it induces an electric current which is then dissipated as it moves through the inductor. This electric current acts as a buffer against the voltage spike and helps to stabilize the overall voltage in the circuit.

The DRA124-820-R is designed to be a high-power inductor capable of handling currents of up to 270A. It uses a ferrite core to provide better thermal performance and better inductance at higher frequencies. This inductor is designed to be robust and reliable, with a long working life.

The DRA124-820-R is a versatile component suitable for a wide range of power applications. It is a reliable and robust component that can be used in high-voltage AC circuits to provide protection against voltage spikes. This inductor is capable of handling peak currents of up to 270A and can withstand voltages up to 2000V AC.
