Wire-wound Chip Inductor
Wire-wound chip inductors are mainly used for oscillation, delay, notch filtering, filtering, and other applications. In conventional circuits, the winding coils of wire-wound inductors provide current limiting for alternating current. Together with resistors or capacitors, they can form high-pass or low-pass filters, phase-shift circuits, resonant circuits, and more. In addition, via transformers, wire windings enable AC coupling, voltage transformation, current transformation, impedance matching, and other functional control.
They feature a wide inductance range, high precision, low loss, high allowable current, strong inheritance in manufacturing processes, simple production, and low cost. However, they are limited in further miniaturization. Wire-wound inductors with ceramic cores maintain stable inductance and extremely low loss at high frequencies, making them widely used in high-frequency circuits.
