Adjustable Inductors provide a unique solution for controlling the level of inductance in an electric circuit. The WVL9FJ222K is an adjustable inductor comprised of two elements, an input resistor and an output choke. This configuration allows the inductance to be adjusted over a wide range from 0.2mH to 0.8mH. The device is ideal for applications such as power supplies, switching power amplifiers, RF applications, and frequency-dependent signal paths.

The adjustable inductor works by using a variable resistor as an input. These adjustable resistors can be adjusted from 0 to 10 kOhms in increments of 1 Ohm. The variable resistor is connected in series to the primary winding on the inductor which demonstrates how changing the resistance value changes the inductance of the inductor. This is done by setting the resistor to a desired resistance value and then adjusting the inductor to the preferred level of inductance.

The adjustable inductor will have a certain level of output depending on the value of the resistor. By adjusting the resistor within the adjustable inductor, the primary winding will adjust the inductance of the secondary windings in the output of the inductor. This allows adjustable inductors to provide accurate and consistent levels of inductance to a circuit design.

When setting up an application that uses adjustable inductors, the first step is to identify the desired inductance. This can be done by measuring the current draw on the load, as this will give an indication of the preferred inductance. The next step is to choose the resistance value for the adjustable resistor. It is important to select a value which is below the optimal level for the inductor, as the larger the resistance, the higher the inductance.

Once the resistance value has been chosen, the adjustable inductor can be adjusted to achieve a specific level of inductance. This can be done by adjusting the input resistor up or down in small increments. The output choke will also need to be adjusted in sync with the input resistor in order to ensure the correct level of inductance. Once the correct level of inductance has been achieved the adjustable inductor can be set to its optimal level.

Many applications requiring adjustable inductors may require an additional level of precision. In such cases, high precision adjustable inductors are available with resistors that offer far greater resolution and accuracy. These precision adjustable inductors can be used in applications such as power supplies, switching power amplifiers, RF applications, and more.

Adjustable inductors such as the WVL9FJ222K are an invaluable component in many applications. By controlling the inductance of the inductor, the circuit can be optimized for the desired output. The adjustable inductor is also relatively simple to set up, and with the wide range of resister configurations available, precision tuning of the inductor is easier than ever.
