Thin Film Resistor

Chip power inductors, also known as power inductors and high-current inductors. A chip inductor is a property of a closed circuit. When current passes through the coil of a chip inductor, a magnetic field is induced in the coil, and the induced magnetic field in turn generates an induced current to resist the current passing through the coil. The function of a chip inductor in a circuit is to generate a changing magnetic field when an unsteady current passes through it, and this magnetic field will in turn affect the current. When a chip inductor is connected in series in a power supply circuit, the inductor is directly connected to direct current (DC) and has high impedance to high-frequency pulses, thus playing the role of passing DC and blocking AC pulses.
