A SMD Inductor is an electronic component used in electronic circuits to store and release energy in the form of a magnetic field. It is designed to be mounted directly onto the surface of a printed circuit board (PCB) using automated pick-and-place machines, making them well-suited for high-volume manufacturing processes. The electrical properties of a SMD Inductor are determined by its inductance value, which is measured in henries (H) or millihenries (mH).
