The concept of safety capacitor is believed to be well-known to many people. Safety capacitor refers to a safety capacitor that, after a capacitor fails, will not cause electric shock and will not endanger personal safety. But what role does the specific safety capacitor play? What are the characteristics? There are not many people who particularly understand. Today, let's popularize the knowledge related to safety regulations and capacitors.
The characteristics and functions of safety capacitors
1. The types and functions of safety capacitors.
Safety capacitors are mainly divided into X and Y safety capacitors, and their biggest feature is to protect the safety of the circuit. After the capacitor is damaged or fails, the circuit will not endanger our personal safety.
2. Can I cancel the safety capacitor?
Since safety capacitors fail, there won't be any safety issues. Can we just skip them and save a lot of money? This idea is incorrect. Safety capacitors are mainly used in circuits such as switching power supplies, which generally require mandatory certification, otherwise the product cannot be sold. Safety regulations play a role in power filtering, respectively filtering common mode and differential mode interference. Without these capacitors, the product may have EMC issues and cannot pass relevant certification. So safety capacitors cannot be saved.
