Function of chip inductor

SMD inductor is an electromagnetic induction component wound with insulated wires. It is a commonly used inductive element. Function of SMD inductor: Connect DC resistance to AC This is a simple statement. It isolates and filters AC signals or forms a resonant circuit with capacitors and resistors Function of tuning and frequency selecting inductor: The LC tuning circuit can be formed by the parallel connection of inductance coil and capacitor. Any current of the chip inductor in the circuit will generate a magnetic field, and the magnetic flux of the magnetic field will act on the circuit.
When the current passing through the chip inductor changes, the DC voltage generated in the chip inductor will prevent the current change. When the current passing through the inductance coil increases, the self induced electromotive force generated by the inductance coil is the same as that of electricity. When the current passing through the inductance coil decreases, the self induced electromotive force is in the same direction as the current, preventing the decrease of current, and releasing stored energy to compensate for the decrease of current. The flow direction is opposite to prevent the increase of current, and at the same time, part of electric energy is converted into magnetic energy and stored in the inductor; Therefore, after inductance filtering, not only the ripple of load current and voltage decreases, the waveform becomes smooth, but also the conduction angle of rectifier diode increases.
