Adjustable inductors are versatile components used to control inductance, or the opposition to the flow of changes in current. They allow the user to shape and adjust a circuit’s inductance, frequency response, and power requirements. One of the most popular adjustable inductors is the WVL9FJ471K, which offers an array of features designed to make it suitable for a variety of applications.

The WVL9FJ471K is a small, surface-mountable inductor designed for low-power applications. It is a 2-pin, adjustable inductor, which can be configured with either a linear or nonlinear inductance range. The linear inductance range offers a maximum of 1.3 millihenries and a minimum of 0.4 millihenries, which is ideal for applications such as radio-frequency identification (RFID), measurement and control electronics, and power circuitry. The nonlinear inductance range is available from 0.8 millihenries to 1.2 millihenries, making it suitable for signal conditioning and filtering applications.

The WVL9FJ471K also features an embedded digital interface which enables it to be programmed and calibrated remotely. This makes it possible to calibrate the inductance of the device without the need for manual adjustments. The interface includes two pins which can be used to set the inductance range and the frequency of the inductor. The interface also includes a status register, which can be used to monitor the performance of the adjustable inductor in real-time, allowing for tuning and optimization of the inductor’s performance.

The WVL9FJ471K also features integrated protection circuitry which helps to protect the device from overcurrent, overvoltage, and short-circuit conditions. In the event of an overcurrent or overvoltage condition, the protection circuit will shut down the device, protecting the inductor and other circuit elements from damage. In the event of a short-circuit condition, the protection circuit will redirect the current, allowing the device to continue operating.

In addition to its integrated protection circuitry, the WVL9FJ471K also features an adjustable current limit feature. This feature allows the user to adjust the current through the device, ensuring that the inductor does not cause any damage to the circuit during operation. The adjustable current limit feature also allows the user to tailor the inductor’s performance to the system’s requirements, helping to improve system efficiency.

In summary, the WVL9FJ471K is an adjustable inductor that is suitable for a variety of applications. Its surface-mountable design makes it suitable for low-power applications, and its embedded digital interface enables it to be programmed and calibrated remotely. The device also features protection circuitry to guard against overcurrent, overvoltage, and short-circuit conditions, as well as an adjustable current limit feature to improve system efficiency. As such, the WVL9FJ471K is an ideal choice for designers looking for a reliable and versatile adjustable inductor for their circuit designs.
