Q: What is a safety capacitor?
A: Safety capacitors are used in such occasions that after the capacitor fails: it will not cause electric shock and will not endanger personal safety. It includes X capacitors and Y capacitors. The x capacitor is the capacitor connected between the two lines of the power line (LN), and metal film capacitors are generally used; the Y capacitor is the capacitor connected between the two lines of the power line and the ground (LE, NE), and usually appears in pairs. Due to the limitation of leakage current, the Y capacitor value cannot be too large. Generally, the X capacitor is uF and the Y capacitor is nF. The X capacitor suppresses differential mode interference, and the Y capacitor suppresses common mode interference.
Q: Why are some capacitors called safety capacitors?
A: The "safety" in safety capacitors does not refer to the capacitor material, but that the capacitor has passed the safety certification; in terms of material, the safety capacitors are mainly CBB capacitors and ceramic capacitors.
