Adjustable Inductors: WVL9FJ3R9K Application Field and Working Principle

Adjustable inductors are two-terminal components that are used to adjust the inductance of a circuit. One of the most common adjustable inductors is the WVL9FJ3R9K, which features small size, low core loss, high Q-factor, and high linearity over a wide range of inductance. This makes the WVL9FJ3R9K an ideal choice for high frequency applications like antenna tuning, radio frequency (RF) and microwave systems, and communications applications.

WVL9FJ3R9K Application Field

The WVL9FJ3R9K adjustable inductor is a great choice for high-frequency applications such as antenna tuning, RF, and microwave systems. It is suitable for mobile device RF applications, receiver antenna tuning, as well as signal interference cancellation, impedance matching, and antenna matching. Additionally, it is ideal for communications applications such as 5G communication, optical communication, and mobile base station communications.

The WVL9FJ3R9K adjustable inductor is composed of three main parts: a main body, a lid, and an internal mechanism. The main body is made of iron powder with a general tolerance of +/- 20%, ensuring high linearity and an inductance range of 5-1100 uH. The lid is made of high permeability ferrite and features a SRF greater than 9.0GHz. The internal mechanism uses a precision winding and winding technique to ensure an inductance value that is maintained up to the tenth of a second.

Working Principle

The WVL9FJ3R9K adjustable inductor works according to the principle of the variable magnetic component. The variable magnetic components are two terminal components, whose inductance can be adjusted through internal adjustment. The two terminal components are encased in a ferrite lid and surrounded by an inner control mechanism. When the inner control mechanism is adjusted, the magnetic field generated by the two terminals changes, thus changing the inductance of the inductor.

The WVL9FJ3R9K adjustable inductor works on the principle of low-ohmic, high-Q, and low-loss inductance. It features high Q-factor because the iron powder used in the construction of the inductor has high permeability, and thus low losses. Additionally, the winding accuracy also ensures high Q-factor performance. The low-loss inductance feature makes the WVL9FJ3R9K ideal for antenna tuning, RF, and microwave systems.

Conclusion

The WVL9FJ3R9K adjustable inductor is an ideal choice for high-frequency applications such as antenna tuning, RF, and microwave systems. It features small size, low core loss, high Q-factor, and high linearity over a wide range of inductance, which makes it ideal for communications applications such as 5G communication, optical communication, and mobile base station communications. Additionally, its low-ohmic, high-Q, and low-loss inductance properties make it an excellent choice for antenna tuning, RF, and microwave systems.
