How to choose a safety capacitor?
The selection method of safety capacitor is as follows:
(1) Withstand Voltage Selection:
X-type stabilized capacitors are divided into three types according to withstand voltage: X1, X2, and X3. The permissible peak pulse voltage over-potential level of the stable capacitor safety level: 2.5kV<X1≤4.0kV, X2≤2.5kV, X3≤1.2kV.
Y-type safety capacitor safety level: Y1≥250V, allowable peak pulse voltage>8KV; 150V≤Y2≤300V, allowable peak pulse voltage>5KV, Y4<150V, allowable peak pulse voltage>2.5KV.
Choose stable capacitors with different withstand voltage values according to the circuit, and cannot be too large or too small. X2 capacitors are mostly selected for X capacitors.
(2) Certification Type
Regardless of the type of electronic device, it must be verified. Safety certification also includes product safety verification, environmental certification, and power energy verification. Different countries have different electrical safety requirements. Some require ccc certification. Many, such as CQC certification in China, VDE certification in France, UL certification in the United Kingdom, ENEC certification in EU countries, and KC certification in Japan. In the case of choosing safety capacitors, different verified electronic devices should be selected according to different places and different countries.
