The capacitor is broken can it be powered on
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
A busted capacitor can be obviously broken (leaking brownish fluid, corroded, or with the leads severed), but sometimes it''s subtle. The top of a blown capacitor will be slightly bent outwards in a convex shape, rather than flat or slightly indented inwards like a working capacitor. See the photos above for examples.
