Understanding CBB65 Motor Run Capacitors: Applications, Features and Selection Tips
Feb 03, 2026
In modern HVAC and motor-driven systems, stable motor operation is essential for efficiency, safety, and long-term reliability. Among various AC motor capacitors, the CBB65 motor run capacitor has become one of the most widely used solutions for air conditioners, water pumps, and ventilation systems.
In this blog, we will take a closer look at what CBB65 capacitors are, why they are so popular, and how to choose the right one for your application.
What Is a CBB65 Motor Run Capacitor?
A CBB65 capacitor is an AC motor run capacitor made with metallized polypropylene film (MPP). Its main function is to provide phase shifting for single-phase motors, allowing them to run smoothly and efficiently during continuous operation.
Unlike electrolytic capacitors, CBB65 capacitors are designed for...
