Why choose safety capacitors? What are the advantages of safety capacitors?

Safety capacitors are a more familiar type of capacitor family, usually used in power supplies, and various home appliances such as TVs also have safety capacitors. Before the emergence of safety capacitors, ordinary capacitors were used in power supplies and home appliances. However, after the emergence of safety capacitors, people found that safety capacitors are better than ordinary capacitors, and safety capacitors gradually replaced ordinary capacitors in power supplies and home appliances.

1. What is the difference between safety capacitors and ordinary capacitors?

After a safety capacitor fails, the internal charge discharges rapidly, and people will not feel an electric shock when they touch it, and it will not cause electric shock or pose a threat to personal safety. Ordinary capacitors can retain their charge for a long time after the external power supply is disconnected, and if you are not careful, it will cause electric shock and harm to the human body.

2. What is the function of safety capacitors?

Safety capacitors are divided into safety X capacitors and safety Y capacitors. They are used in power supply filters to play the role of power supply filtering. Safety X capacitors are used in power supplies to suppress differential mode interference, suppress electromagnetic interference, resistive capacitance voltage reduction, filtering, etc.

Safety Y capacitors are mainly used to resist voltage, suppress common mode interference, prevent high voltage shocks, and protect other electronic components.

3. Why do safety capacitors need safety certification?

Safety capacitors must pass safety inspection and certification to be considered true safety capacitors. The purpose of doing this is to ensure the quality and quality of safety capacitors, and to protect the rights and interests of consumers from infringement, and to avoid serious consequences caused by inferior products counterfeiting safety capacitors.

Because safety certification is strict, and the safety certification standards of countries such as Germany and South Korea are different, passing multiple safety certifications further proves the strength of the manufacturer. The safety capacitors produced by Zhixu Components have passed the safety certifications of other countries such as Germany and South Korea, and are sold well at home and abroad.

4. Is it okay for the switching power supply not to have safety capacitors?

If the power supply does not use safety capacitors, there will be no problems with the power supply in a short period of time. Inferior power supplies may not use safety capacitors to save costs, but this will reduce the EMI suppression capability of the power supply, there is a risk of damaging other components, and greatly reduce the working time of the power supply. Not using safety capacitors has no other benefits except saving costs.
