Metallized film capacitors emit the sound of Zizz when they pass alternating current.

Metallized film capacitors emit the sound of Zizz when they pass alternating current. One of the reasons is that the self-healing sound that is specific to the membrane capacitance is not going to be very loud, and it's going to fade over time, and if you disappear, you have to pay attention to the attenuation of the capacitance capacity, if there's no attenuation, or very, very much. A small amount of attenuation indicates that the capacitance is qualified this sound does not affect the use of the two cases is the capacitance of the lead electrode or electrode to the object of the exchange sound. It may be that the creeping distance between t-t or t-c is not enough to cause the AC sound, in this case, you can try to change the position of the capacitance, if it is still not eliminated. We generally believe that the housing of the capacitor is not up to standard.
