The safety plug-in capacitor is a porcelain dielectric capacitor, the rated voltage of Y1 capacitor is 400V, and the Y2 capacitor is 250V. CBB capacitors and safety ceramic capacitors are both film capacitors, while CBB capacitors are polypropylene metal film capacitors, and safety ceramic capacitors are metal film capacitors. From the appearance, safety ceramic capacitors are generally divided into blue plug-in capacitors, black chip capacitors and yellow rectangular X2 capacitors, while CBB capacitors are generally red in appearance.
Safety plug-in capacitor is a safe and reliable capacitor, and light weight, small size, mainly used in gallium nitride chargers, electronic instruments and electronic equipment, used in switches, contacts and other parts that produce spark discharge, can withstand the high pulse voltage generated by the fault of external line equipment, absorb pulse interference, reduce electromagnetic disturbance. It is widely used in power tools, chargers, lighting, hair dryers, water heaters and other household appliances.
CBB capacitors use metallized polypropylene film as a medium and electrode, and then enclosed with epoxy resin and flame retardant tape, which not only has the characteristics of strong temperature resistance, small size, large capacity, strong reliability, high electrical strength, etc., but also has good self-healing performance. CBB capacitors are widely used in power tools, lighting fixtures, refrigerators, air conditioners, washing machines and other home appliances and power systems.
Through the above analysis, we can choose according to our own needs when choosing capacitors, CBB capacitors can protect the circuit because of their high electrical strength, and safety ceramic capacitors can effectively protect the personal safety of users after the capacitor fails. In addition, CBB capacitors are resistant to inrush current, which can protect the circuit. When choosing, you can choose according to your own needs.
