The discharge of X1 safety capacitor is different from that of ordinary capacitor. When the external power supply is disconnected, the charge inside the ordinary capacitor will remain for a long time. In this case, if touched by hand, the electric shock will occur. So, what indicators should not be ignored when purchasing safety capacitance?

1.Nominal capacitance

If the capacitance does not meet the standard, it will seriously affect the quality of its use, therefore, we need to consider one of the indicators in the purchase of X1 safety capacitance is the nominal capacitance, that is, the capacitance value marked on the safety capacitor products. In general, ceramic capacitors have a low capacitance, while paper, plastic, and some ceramic media forms are in the middle.

2.The rated voltage

Rated voltage is also one of the important parameters that can not be ignored when purchasing X1 safety capacitor. Rated voltage refers to the DC voltage that can be continuously applied to the safety capacitor at any temperature between the lower class temperature and the rated temperature, or the value of the large AC voltage, the peak of the pulse voltage, if the rated voltage does not match the practical voltage, it will cause a fault.

3.corona

When the X1 safety capacitor is used in various high voltage situations, special attention should be paid to the effect of corona. Therefore, we should also consider more corona indicators when purchasing safety capacitance. This is mainly because corona is caused by the presence of gaps between the dielectric/electrode layers, which can cause dielectric breakdown of the capacitor in addition to parasitic signals that can damage the device.

Everyone in purchasing good quality X1 safety capacitors, in addition to considering the nominal capacitance, rated voltage and corona aspects such as technical indicators, the more people considering the temperature requirements, must according to the category temperature range to choose, to ensure that procurement back X1 safety capacitance can adapt to the continuous working temperature range, Avoid all kinds of unexpected situations in the process of use.
