Component leakage

When the capacitor is leaking, the insulation performance between the two poles of the capacitor is decreased, the leakage resistance exists between the two poles, there is a DC current passing through the capacitor, the straightness of the capacitor becomes worse, and the capacity of the capacitor decreases. When the coupling capacitor leakage, it will cause the circuit noise. This is the small capacitor fault rate is relatively high, and fault detection is difficult.
