Fixed inductors are electronic components that are widely used in AC and DC circuits. They are designed to store energy in the form of an electro-magnetic field, and then re-release it when needed. ELJ-PA100KF is a type of fixed inductor that has a wide range of applications and a simple working principle.

Application field of ELJ-PA100KF

ELJ-PA100KF is an inductance-type active component ideal for a variety of applications. It is commonly used in AC and DC circuits, and is especially suitable for Switch mode power supplies (SMPS), radio frequency circuits, pulse circuits, and switching circuits. It can be found in various consumer electronic devices such as computers, printers, TVs and audio-visual equipment.

Working Principle of ELJ-PA100KF

The ELJ-PA100KF consists of a ferrite core wound with a copper wire. These components create an inductor in the circuit that reacts to changes in current. When an alternating current is applied to the inductor, its magnetic domain is alternating in the same direction as the current. This creates an opposing electromagnetic field, which in turn results in an inverse voltage being generated.

The inductor can also work on a DC circuit. In this case, the domain magnets align themselves in the same direction as the current, creating a stronger opposing electromagnetic field. This again creates an inverse voltage, which opposes the applied voltage and is called inductive reactance. The amount of inductive reactance is determined by the values of the applied voltage and the amount of current.

An inductor can also be used as a high-pass filter. It works by allowing high frequency signals to pass through and blocking low frequency signals. This is achieved by the inductance of the inductor, which forces any DC components of the signal to be seeded through the inductor before they reach the output.

ELJ-PA100KF are also commonly used in pulse generators. A pulse generator circuit is used to generate narrow pulses of current, and the inductance of the inductors helps control the rise and fall times of the pulses and the output current. This makes the use of ELJ-PA100KF ideal in pulse signal applications.

ELJ-PA100KF are also used in transformer circuits. They act as a step-down transformer by allowing high voltage input currents to be converted into lower output voltage levels. The inductors in the circuit act as the primary winding of the transformer, and by increasing or decreasing the number of windings, the output voltage can be changed. This makes the ELJ-PA100KF an ideal component for transformer applications.

Conclusion

ELJ-PA100KF are versatile fixed inductors that are used in a wide range of applications. They are usually found in AC and DC circuits, and are also commonly used in SMPS, RF circuits, pulse circuits, and switching circuits. The working principle of these inductors is based on the generation of an inverse voltage through the use of an electromagnetic field, which makes them ideal for high-pass filters, pulse generators, and transformer circuits.
