What kind of situation you need to quit running cbb capacitor?

The CBB capacitor is actually a polypropylene capacitor, and is a capacitor in which a metal foil is used as an electrode, and a polypropylene film is stacked from both ends and then wound into a cylindrical structure. Non-polar, high insulation resistance, excellent frequency characteristics (wide frequency response), and low dielectric loss. It is widely used in resonant circuits, bypass circuits, and high-frequency high-voltage circuits. is actually a polypr
