Adjustable Inductors

An adjustable inductor, also known as a variable inductor or an adjustable autotransformer, is a two-terminal electronic component. It is designed to provide adjustable inductance over a wide range of settings, allowing for precise tuning and control. This type of component is often found in commercial and consumer electronic circuits, where it is used to resist high frequency signals, filter radio signals, or adjust the output voltage. Adjustable inductors can also be used in radio antennas and electromedicine. One specific adjustable inductor, the WVL9FJ472K, is now commonly used in many commercial and consumer electronic applications.
