CD Aluminum Electrolytic Capacitor
Products Description
CD aluminum electrolytic capacitors are polarized, high-capacity, high-voltage aluminum electrolytic capacitors primarily used for closing energy storage, opening control, and DC energy storage buffer circuits in high-voltage electrical equipment such as vacuum circuit breakers, permanent magnetic actuators, and load switches. They feature high capacity, high withstand voltage, low leakage current, long life, and good stability.
CD aluminum electrolytic capacitors are the "power reservoir" for medium-voltage switchgear – storing energy and releasing it in milliseconds to trip breakers, close switches, and keep your grid safe.
