Adjustable inductors are an integral part of any electrical system. Their ability to be switched between different inductance values makes them ideal for many applications. One particular model of adjustable inductor is the WVL9FJ332K, which has many uses and a distinct working principle.

Application Field

The WVL9FJ332K adjustable inductor is suitable for a wide range of applications. It is prevalently used in power supplies, where its switchable inductance allows for a fine control of current levels, while still attaining some filtering efficiency. When integrated with a voltage regulator, the WVL9FJ332K can prove to be incredibly efficient at reducing ripple. These inductors are also used in switching power converters for efficiently controlling output voltage and frequency. Other uses include in noise suppression circuits, voltage dividers and low-pass filters.

Working Principle

The WVL9FJ332K adjustable inductor works on the principle of magnetically coupled air coils. The inductor consists of a core which contains two dry air-coils. One coil is fixed in the core and is known as the primary coil, while the other one, the secondary, can be tuned according to application needs. When a current is passed through the primary coil, it creates a varying magnetic field in the iron core, inducing a current in the secondary coil. The magnitude of the current in the secondary coil is determined by the amount of coupling between the two coils. The secondary coil is tuned by changing the number of turns in the coil.

The adjustable inductor can be tuned using a knob or a potentiometer. This feature makes it ideal for applications where the inductance value needs to be adjusted frequently or without changing the component itself. The resistance or impedance of the WVL9FJ332K can also be varied or tuned using the same methods.

Conclusion

The WVL9FJ332K adjustable inductor is widely used in a variety of electrical circuits. Its adjustable features makes it a versatile component which can be used for many different applications. The adjustable inductor works on the principle of magnetically coupled air coils. Two coils are situated in the core, one of which is variable and can be tuned using either a knob or a potentiometer. The WVL9FJ332K is an essential component in many electrical systems.
