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
產(chǎn)品結(jié)構(gòu)與工藝特點(diǎn)
該電容器采用多層結(jié)構(gòu)設(shè)計(jì)，云母介質(zhì)經(jīng)過(guò)多次驅(qū)潮浸處理和反復(fù)芯組老化工藝，確保產(chǎn)品性能穩(wěn)定。金屬化電極通過(guò)高溫焙燒形成牢固結(jié)合，全密封包裝有效防止環(huán)境因素影響。靜電屏蔽設(shè)計(jì)可減少外部干擾，三端鈕結(jié)構(gòu)（包括屏蔽端鈕）提供了靈活的連接方式。生產(chǎn)工藝上采用精密印刷被銀技術(shù)，保證電極均勻性和一致性，這種結(jié)構(gòu)設(shè)計(jì)使得產(chǎn)品具有較低的溫度系數(shù)和良好的頻率特性。1126
Application Scenarios
This component finds extensive use in bridge circuits and various measurement systems where stable capacitance values are required. Its design characteristics make it particularly suitable for precision measurement applications in laboratory environments and industrial settings. The capacitor s stable performance across wide frequency ranges allows for versatile usage in different circuit configurations. When integrated into measurement systems, it provides reliable reference values for capacitance measurements and circuit calibration purposes. The product s robust construction ensures consistent performance even under varying environmental conditions.137
使用與儲(chǔ)存建議
建議在測(cè)量時(shí)根據(jù)實(shí)際需求選擇二端鈕或三端鈕連接方式，使用二端鈕式時(shí)需考慮分布電容的修正值。儲(chǔ)存時(shí)應(yīng)保持環(huán)境溫度在0℃~45℃之間，相對(duì)濕度30~80%，避免接觸腐蝕性氣體和有害雜質(zhì)。連接電路時(shí)建議使用短導(dǎo)線(xiàn)以減少附加電容影響，定期檢查接線(xiàn)端鈕的接觸可靠性。產(chǎn)品在正常使用和維護(hù)條件下可保持長(zhǎng)期性能穩(wěn)定，適合需要高精度電容參考的各類(lèi)電子測(cè)量場(chǎng)合。11211
