Fixed Inductor

A fixed inductor, also called a choke, is an electrical component typically used to maintain a constant current in a circuit. It works by utilizing a magnetic field to store energy temporarily when a current is applied, so that it can be released back into the circuit later. The ETQ-P3W2R2WFN is a type of fixed inductor which has wide range of application in many areas.

Application Field

The ETQ-P3W2R2WFN fixed inductor is mostly used in solar panels, LED displays, and home appliances like refrigerators. It is also used to help reduce interference from radio and TV signals, as this type of inductor can block certain frequencies, while allowing others to pass through. Furthermore, they are used in power strips for surge protection, as they can help regulate the flow of electricity in potentially unstable power sources. In addition, this type of inductor can also be used in audio/video applications, from guitar effects pedals to studio computers.

Working Principle

The working principle of the ETQ-P3W2R2WFN fixed inductor is that it provides a low inductance path for frequencies below its characteristic frequency. It does this by having a coil with relatively low resistance that will pass some signals from external sources, while blocking others. Essentially, the inductor acts as a filter, allowing an uninterrupted flow of current and reducing the electrical noise from outside sources.

When current is applied through the inductor, it causes an electromagnetic field to be generated, which stores the energy from the current. The generated magnetic field will then produce a magnetic flux that will attract the steel core. The core is then magnetized, forming a closed magnetic path that will prevent the flow of current. This interaction of the steel core with the magnetic flux causes the inductance of the circuit to increase.

The inductor will then continue to store the energy from the current until it is needed to be released back into the circuit for usage. This release of energy will then reduce the inductance of the circuit, as the core will be demagnetized and the stored energy will be dissipated.

Conclusion

The ETQ-P3W2R2WFN fixed inductor is a versatile component that has a variety of applications in consumer electronics, home appliances, and audio/video equipment. It has a working principle that is based on storing energy from the current in an electromagnetic field, then releasing it back into the circuit when needed. This inductor provides a low inductance path for frequencies below its characteristic frequency, allowing uninterrupted flow of current and reducing the electrical noise from outside sources.
