1. Chip inductors are magnetic induction components with insulated wires, which are one of the commonly used passive components.

2. The function of the chip inductor: The function of DC resistance and AC is mainly to isolate AC signals, and at the same time form a resonant circuit with filters, capacitors, resistors, etc. The role of inductance for tuning and frequency selection.
3. The LC tuning circuit is composed of an inductor coil and a capacitor in parallel, and the power inductor plays a role of resonance tuning in the circuit.
4. Any current of the chip inductor in the circuit is the magnetic field generated by the circuit where the inductor is located, and the magnetic flux of the magnetic field acts on the circuit. At this time, the circuit is loaded with a certain magnetic flux. Generally, the more saturated the magnetic flux, the more stable the inductance performance of the circuit.
5. When the current passing through the chip inductor changes, the current change will be blocked by the DC voltage potential generated by the chip inductor. Stop changing the current outside of this circuit; because the changed current may be a large current; if the general circuit cannot withstand it; it may affect other components in the circuit; it is the entire circuit substrate burned.
6. When the current through the chip of the chip power inductor increases, the self-induced electromotive force generated by the chip power inductor decreases, and the current generated by the inductor decreases, and the self-induced potential and current direction are the same. In order to prevent the decrease in current, the stored energy is released to compensate for the decrease in current. The current is in the opposite direction to prevent an increase in current.
7. At the same time, part of the electric energy is converted into magnetic field energy and stored in the inductor. Therefore, after inductance filtering, not only the load current and voltage pulsation is reduced, the waveform becomes smooth, and the conduction angle of the rectifier diode is increased.
8. Chip power inductors act differently from ordinary chip inductors acting in a single circuit, acting as EMC, EMI, and having the function of power storage.
9. Shielding chip inductors can shield the current instability in some circuits and play a good blocking effect. A metal shield with a complete shield inductance will surround the positive conductor and induce a negative charge equal to the charged conductor inside the shield.
10. The outside has the same positive charge as the charged conductor. If the metal shield is grounded, the positive charge from the outside will flow into the earth, and there will be no electric field outside.
