CBB61 capacitor series adopts metallized zinc-aluminum film with thickened connection as electrode and dielectric, and is encapsulated by plastic shell, which has the advantages of small volume, light weight, small loss, good capacitance stability and good self-healing performance. It is often used in single-phase motors with relatively low power supplied by 50/60HZ AC power supply, as starting and running capacitors, such as air conditioning fans, electric fans, exhaust fans, etc.
