Fixed Inductors

A Fixed Inductor, also known as a Choke, is an electrical component designed to resist changes in current flowing through it. It does this by producing a magnetic field that opposes the change in current. This magnetic field, created by the inductor when a current is passed through it, is known as inductance. The PA4547.102NLT Fixed Inductor is an example of such a component.

Application Field

The PA4547.102NLT is typically used as a filter, providing inductive reactance to limit current flow, or as a coil, providing inductance to increase current flow in a circuit. As a filter, the PA4547.102NLT can be used in AC power supplies, voltage regulation circuits and harmonic suppression circuits. As a coil, it is often used in radio frequency circuits and switched mode power supplies.

Working Principle

The PA4547.102NLT works by converting electrical energy into magnetic energy, then magnetic energy into electrical energy. When a current passes through the inductor, it creates a magnetic field. This magnetic field induces a voltage in the wound coils, which is proportional to the rate at which the current through the inductor is changing. This induced voltage opposes any change in the current, creating an inductive reactance, which limits the current flow.

The amount of inductance in the inductor is determined by the number of turns in the coil and the permeability of the core material, as well as other factors such as size and shape. Increasing the number of turns increases the inductance, while decreasing it decreases it. The core material has a large effect on the inductance, as it determines how easily the coil can allow the magnetic field to pass through it.

Conclusion

The PA4547.102NLT Fixed Inductor is a component designed to resist changes in current flow by producing a magnetic field that opposes the change. It is most commonly used as a filter or a coil, in AC power supplies, voltage regulation circuits, and harmonic suppression circuits, radio frequency circuits, and switched mode power supplies. The inductance of this component is determined by the number of turns in the coil, the permeability of the core material, and other factors such as size and shape.
