The chip inductor is an electromagnetic induction element wound with an insulated wire. It is a commonly used inductive component. The role of the chip inductor: through the DC resistance AC is a simple statement, the AC signal is isolated, filtered or combined with capacitors, resistors, etc. to form a resonant circuit. Tuning and frequency selective inductance: the inductor and capacitor in parallel can form LC Tuning the circuit. Any current in the circuit of the chip inductor generates a magnetic field that acts on the circuit.

When the current through the chip inductor changes, the DC voltage potential generated in the chip inductor will prevent the current from changing. When the current through the inductor increases, the self-induced electromotive force generated by the inductor coil is opposite to the current direction, preventing the increase of the current, and converting a part of the electric energy into a magnetic field can be stored in the inductor; when the current through the inductor is reduced, The self-induced electromotive force is in the same direction as the current, preventing the current from decreasing and simultaneously releasing the stored energy to compensate for the decrease in current. Therefore, after the inductor filtering, not only the ripple of the load current and voltage is reduced, the waveform becomes smooth, and the conduction angle of the rectifier diode increases.
