How to Avoid Using Bad Y Capacitors(I)

Y capacitor is the type of Safety capacitor, which means to use such a place, that is, after the capacitor fails, it will not cause electric shock, do not endanger the safety of human beings. What ways do we find Y capacitor problems and even circumvent problems?

1. Examination of appearance.

After getting the sample, check whether the powder coating on the appearance of Y capacitor product is average, whether the appearance is complete, whether the product parameter print and the safety gauge certification mark have any unclear place.

2. View the corresponding Y capacitor instructions.

The type of Y capacitor will be described in the product specification, including: nominal voltage, voltage test, deviation, temperature coefficient, inherent loss, insulation resistance, capacitance size and foot size.
