A. Product Features 1. A new and well - made product. 2. Constructed with good materials, it has features like high precision, stability, low impedance, and a relatively long service life. It can be used for up to 2000 hours in a 105°C environment. 3. Rated voltage: 50V DC. Capacitance: 10,000 microfarads. 4. It has a relatively low equivalent series resistance (ESR) and a fast charging speed, taking only a few seconds. It is environmentally - friendly, safe, and easy to use. 5. Safe and reliable: The coupling capacitor can isolate strong and weak currents, provide high - frequency signals for the circuit, prevent power - frequency current from entering the weak current system, and help ensure personal safety. 6. Widely used in DC blocking, coupling, bypass, filtering, tuning circuits, energy conversion, control circuits, etc. B. Specifications 1. Rated voltage: 50V 2. Capacitance: 10,000 microfarads 3.
