The so-called safety capacitors are capacitors certified by national safety regulations. The safety certification of different countries is different, and the Chinese safety certification mark is represented by CQC; The safety certification mark in the United States is represented by UL; The safety certification mark in Germany is represented by VDE; The safety certification mark in South Korea is KC, which represents them.

Regarding the issue of capacity conversion: When you encounter a 2.2uF 2200nF 2200000pF 225 310VAC Metallized MKP X2 value, will you convert it? 1UF=1000NF=100000PF， For example, 224 represents 220000PF=0.22UF. Now you understand the value of 2.2uF 225nF X2 Suppression Capacitors 310V Box X2! There is no difference between the rated voltage of 275VAC and 280VAC/310VAC, only the printing requirements vary in different countries.

The performance of safety capacitors with different volumes varies, with larger volumes having higher withstand voltage values. The distance between their two legs is 10mm or 15mm, and the capacitance range is 0.0022uf~4.7uf. There are three types of capacitance errors, one represented by J is ± 5%, K represents 10% error, and M represents its error range of 20%.

For X-type safety capacitors, they are generally connected between the live wire L and the neutral wire N at the power input terminal. This way, when the interference source in the circuit is eliminated through parallel safety capacitors when the power supply crosses the input terminal, not only the normal voltage must be considered, but also the generation of abnormal pulse voltage (such as lightning), which may cause the capacitor to smoke or catch fire.
