What is the difference between safety ceramic capacitors and CBB capacitors?

Safety ceramic capacitors are ceramic capacitors, the rated voltage of Y1 capacitor is 400V, and the Y2 capacitor is 250V. Both CBB capacitors and safety ceramic capacitors are film capacitors, while CBB capacitors are polypropylene metal film capacitors, and safety ceramic capacitors are metal film capacitors. From the outside, safety ceramic capacitors are generally divided into blue plug-in capacitors, black SMD capacitors and yellow rectangular X2 capacitors, while CBB capacitors are generally red in appearance.

 Safety ceramic capacitors are safe and reliable capacitors with light weight and small size. They are mainly used in gallium nitride chargers, electronic instruments and electronic equipment. They are used in switches, contacts and other parts where spark discharge occurs. The higher Capacitor pulse voltage generated by the fault of the line equipment absorbs the pulse interference and reduces the electromagnetic disturbance. It is widely used in electric tools, chargers, lighting, air ducts, water heaters and other household appliances.

CBB capacitors use metallized polypropylene film as the medium and electrodes, and then seal them with epoxy resin and flame retardant tape. They not only have the characteristics of strong temperature resistance, small size, large capacity, strong reliability and high electrical strength, but also good Self-healing properties. CBB capacitors are widely used in electric tools, lighting fixtures, refrigerators, air conditioners, washing machines and other home appliances and power systems. Through the above analysis, we can choose capacitors according to our own needs when choosing capacitors. CBB capacitors can protect the circuit because of their high electric strength, while safety ceramic capacitors can effectively protect the user's personal safety after the capacitor fails. Moreover, the CBB capacitor has a large impact current resistance and can protect the circuit. When choosing, you can choose according to your own needs.
