The IRF46ER122K is one such inductor, popular for its significant role in controlling the current flow in a circuit. It is widely used in various applications that require the ability to regulate power and reduce the magnitude of electric current flow.

IRF46ER122K Application Field

The IRF46ER122K is a power loss inductor designed for low and high-frequency filter applications. It is used in several commercial and industrial applications such as in the aerospace industry. The inductor is widely used in mainboard voltage regulators and on-board circuits. It is also used in communication systems as it can provide accurate voltage regulation and low-pass filtering. The IRF46ER122K inductor is built to withstand a high current density with a wide operating temperature range. Its unique construction ensures reliable operation even under very challenging conditions. The overall performance of the inductor is also said to be unaffected by shock or vibrations, which makes it a great choice when it comes to safety-critical applications.The IRF46ER122K has an inductance of 12.2mH and a rated current of up to 47A. It can handle up to 16V input and its power efficiency stands at 95%. Its size is relatively compact at 11.8mmx10.2mmx4.6mm.

Working Principle of IRF46ER122K

An inductor is a type of electrical component that stores energy in the form of a magnetic field created by an electric current. As the inductor consists of a coil of wire wrapped around a core, the more loops of wire the inductor has, the more energy it will be able to store. The IRF46ER122K inductor works by reducing the magnitude of the electric current flow in the circuit. It does this by using an effect known as inductive reactance, whereby a changing current is resisted by the inductor’s magnetic field. This resistance effectively reduces the magnitude of the current in the circuit and helps in regulating the voltage and current levels.The IRF46ER122K is also used to filter signals in high-frequency circuits. As the inductor works by providing resistance to the signal, it acts as a low-pass filter, which blocks high-frequency signals from passing through the inductor. This prevents unwanted high-frequency noise and signals from affecting the accuracy of the circuit.

Conclusion

The IRF46ER122K inductor is one of the most versatile and reliable components used in a variety of commercial and industrial applications. It is suitable for use in both low and high-frequency circuits and provides reliable voltage regulation and low-pass filtering. The inductor is built to withstand high current density and temperature variations, and its performance is not affected by shock or vibration.
