SMD Wire wound Power Inductors

Product Introduction：

SMD Wire wound Power Inductors, High Current Power Inductors, SMD Inductors is a property of a closed loop,  The magnetic field will be formed by when a current passes through the inductor's coil.The induced magnetic field in turn generates an induced current to resist the current passing through the coil,The function of the wire wound power inductor in the circuit is to generate a changing magnetic field when passing through the unstable constant current, which will in turn affect the current. The wire wound power inductor  is like an inductor in the power supply loop. The inductor is direct to DC and has high resistance to high-frequency pulse, so it can pass DC and prevent AC pulse.

Fuction：

SMD wire wound power inductor is an electromagnetic induction component made of insulated wire. It belongs to a common sensing components. The role of SMD inductors: Alternating current through a DC resistor, which is a simple way of saying that the AC signal is isolated, filtered or resonant circuit consists of capacitors and resistors. Inductor tuning and frequency selection function: inductor coil and capacitor in parallel form LC tuning circuit. Any current from a chip inductor in a circuit generates a magnetic field, and the magnetic flux of the field acts on the circuit.

When the current flowing through the chip inductor changes, the DC voltage potential generated in the chip inductor will stop the current change. As the current through the inductor coil increases, the self-induced electromotive force and the current generated by the inductor coil decrease. When the current through the inductor coil is reduced, the self-induced electromotive force and the current are in the same direction, preventing the current from decreasing and releasing energy storage to compensate for the current reduction. The opposite direction of the current prevents the increase of the current, and converts part of the electric energy into the magnetic field, which can be stored in the inductance. Therefore, after the inductance filtering, not only reduces the pulsation of the load current and voltage, but also increases the conduction Angle of the rectifier diode.
