The working principle of a fixed inductor is based on Faraday\'s law of induction. According to Faraday\'s law, when a varying current passes through an inductor, a varying magnetic field is generated. This magnetic field induces an electromotive force (emf) in the inductor, which opposes the change in current. The magnitude of this opposing force is proportional to the rate of change of the current. This opposing force is what is known as inductance, and it acts as a resistive element, reducing the rate of change of current, resulting in a smoother current flow.

The HKQ04020N9B-T is a type of fixed inductor and it works in the same way as other inductors. When a varying current passes through the inductor, it generates an opposing force that limits the rate of change of current. This inductor is specially designed to provide a high current handling capability and a low DC resistance, making it suitable for a variety of power supply and signal line applications.
