Introduction to BR8-2 Capacitor (English)
The BR8-2 is a precision mica capacitor designed for AC circuits operating at frequencies between 100Hz to 10kHz. It maintains stable performance in environmental conditions ranging from +10℃ to +35℃ with 30-80% relative humidity. Manufactured using selected white mica sheets as dielectric material, the capacitor features silver-plated electrodes created through printing and high-temperature firing processes, ensuring excellent moisture resistance and long-term stability. The hermetically sealed metal container houses the electrical components mounted on a metal panel, with an outer wooden box providing electrostatic shielding. With a nominal value of 0.01μF, this capacitor offers 50V AC working voltage and 500V DC withstand voltage. The compact dimensions of 110×110×100mm and approximate weight of 1kg make it suitable for various measurement circuit applications. Connection options include both two-terminal and three-terminal configurations, though wiring capacitance should be considered during installation.167
