Cbb capacitor is made by winding a metal foil with a polypropylene film in the middle into a cylinder (or block), leading out the electrode, then wrapping it with flame retardant material and sealing it with epoxy resin.
This kind of capacitor has many advantages, such as good frequency characteristics (wide frequency response), low dielectric loss, high insulation impedance, stable performance, surge current resistance, strong overload ability and excellent self-healing performance.
Note: It is widely used in high frequency, pulse, AC, filtering, bypass, coupling and other electronic circuits, and is found in switching power supplies, electronic instruments and equipment, and color TV stereos.
The Cbb capacitor is cylindrical. There are many models according to different characteristics, uses, shapes and sizes. For example, the capacitor model Cbb20/22, the former is a bidirectional (axial) pin and the latter is a unidirectional pin, is widely used in instruments, electrical appliances, energy-saving lamps and other products.
Cbb6 1/65/60. Both are AC motor capacitors, but Cbb6 1 is mostly square in shape and is mainly used for electric fans and fans. And the shape of Cbb60/65 is mostly round. They are all used in the motors of washing machines and air conditioners. The latter are mostly aluminum shells with explosion-proof function.
