Under normal circumstances, the lifespan of X2 safety capacitors is particularly long. But if you buy defective X2 capacitors that are cut corners or of poor quality, they can indeed be damaged when installed on the circuit, but perhaps many people still do not know what the symptoms of WEET 310V AC Class X2 BOX FILM CAPACITOR being broken are. So how should we make a judgment?

• Check the appearance.

If the outer shell of the Yellow Color Safety Capacitor MPX-X2 0.56UF 310V has open flames and cracks, or even if the core inside the capacitor leaks out directly, it indicates that the 310V MPX X2 Metallized Polypropylene Film Interference Capacitors has been completely burned out and can no longer be used.

• Measure capacity.

In most cases, it is difficult to distinguish the damage of X2 safety capacitors from their appearance because X2 capacitors also have self-healing properties. They appear very simple and have a good appearance, but their internal capacity decays greatly. If the capacity of X2 capacitors has become particularly small, it also indicates that they are damaged and cannot be used normally. Usually, we only need to measure its capacity to distinguish it.

If used as a resistive capacitive step-down capacitor, the impact of capacity attenuation on the circuit will be greater, and it will result in a lack of power supply for the entire circuit, ultimately rendering the circuit unusable.
