Adjustable inductors are inductor components that can be adjusted over a wide range of frequencies and inductance values to suit different applications. The WVL9FJ2R2K is an adjustable inductor with a maximum inductance range of 2.5 to 2.9 mH para-sensitivity of 160m 0hm to 220m 0hm. It is one of the most versatile adjustable inductors available in the market, and caters to a wide variety of applications ranging from low noise filters, DC/DC converters, EMI suppression, RF systems, and other switching applications.

The WVL9FJ2R2K adjustable inductor has a characteristic of adjustable inductance with an applied voltage. It has a wide temperature range of -40℃ to +85℃ and an operating frequency range of 0.1 to 1 MHz with a rated current of 4.5A. Its enhanced self resonance frequency makes it suitable for use in high-frequency and high-bandwidth applications.

In addition, the WVL9FJ2R2K adjustable inductor is characterized by its high efficiency and reliability. The low leakage inductance does not introduce any additional inductance to the circuit, increasing efficiency and prevents the generation of undesired oscillations. Moreover, it is qualified for JEDEC MSL 2-3 humidity test, and shows exceptional robustness and stability under long-term operating conditions.

The working principle of the WVL9FJ2R2K adjustable inductor is based on a special type of two-terminal variable inductor. It consists of a punched iron core and two wound coils, that can be adjusted according to the application requirements. The core has a big enough gap that allows for the inductance to be adjusted. The gap size is variable and depends on the voltage applied to the coils.

The voltage applied to the coils changes the gap size of the core, which in turn changes the inductance of the inductor. Thus, the inductance can be changed by adjusting the applied voltage. The magnetic flux generated in the core is proportional to the applied voltage and the rate of change of magnetic flux with respect to voltage defines the permeability index of the coil.

The WVL9FJ2R2K adjustable inductor is an ideal component for applications that require adjusting the inductance. It is an effective device for filtering noise in switching applications as it has low leakage inductance and excellent power dissipation capabilities. It also has a wide operating temperature range, making it suitable for use in radio frequency systems. Furthermore, its adjustable inductance range and high efficiency makes it an ideal component for DC/DC converters and EMI suppression.
