RX7/03十进电容箱
RX7/03十进电容箱产品介绍（中文）
RX7/03型十进电容箱是一款专为精密电路设计的高性能电容调节设备，适用于1500Hz以下的交流电路系统。该产品采用旋钮式十进开关结构，电容变化范围为0-11100pF，通过(0-10)×(10+100+1000)pF的组合实现精确调节，最小步进值为10pF，满足高频电路中对微小电容变化的精细控制需求。电容箱整体设计符合工业级精度要求，在+10℃至+35℃环境温度及30%-80%相对湿度范围内均可稳定工作。产品采用优质聚丙烯薄膜电容元件和银铜复合触点开关，确保长期使用的接触稳定性和参数一致性。典型应用场景包括作为交流电桥的可变容抗臂、滤波移相电路的容抗元件，以及电容表校正等精密测量场合。整机采用电磁屏蔽机箱设计，有效减少外部干扰，面板配备标准1/2端钮和专用屏蔽0端钮，支持二端或三端接入方式。产品尺寸紧凑（约375×100×140mm），重量轻便（≤2kg），便于实验室和现场使用。使用后建议进行放电操作以延长元件寿命，储存时应置于干燥无腐蚀性气体的环境中。111712
RX7/03 Decade Capacitance Box Product Introduction (English)
The RX7/03 decade capacitance box is a precision adjustment device designed for high-frequency circuit applications, operating reliably in AC circuits below 1500Hz. Featuring a rotary switch mechanism with 10-step increments, it provides adjustable capacitance ranging from 0 to 11100pF through (0-10)×(10+100+1000)pF combinations, achieving a fine resolution of 10pF per step. The unit maintains stable performance within an operational temperature range of +10℃ to +35℃ and relative humidity of 30%-80%. Constructed with polypropylene film capacitors and silver-copper composite contact switches, it ensures long-term parameter stability and minimal contact resistance. Typical applications include serving as variable reactance arms in AC bridges, capacitive components in filter/phase-shift circuits, and calibration references for capacitance meters. The shielded enclosure effectively suppresses electromagnetic interference, while the front panel provides standard "1/2" terminals and dedicated shielding "0" terminal for both two-terminal and three-terminal connection methods. With compact dimensions (375×100×140mm) and lightweight design (≤2kg), it s suitable for both laboratory and field use. Proper discharge after operation and storage in dry, non-corrosive environments are recommended for optimal maintenance.32115
产品技术特点补充说明
该电容箱采用模块化十进开关组件设计，每个十进制单元由多个精密电容并联构成1-10个步进值。电气部分整体安装在屏蔽机箱内，有效降低分布电容影响（零位电容≤80pF）。工作电压限制为50V有效值，在800-1000Hz频率范围内可达到最佳精度表现。温度系数经过优化，当环境温度在+20℃±5℃范围内波动时，电容值变化不超过基本误差的1/2。产品特别考虑了实际应用场景需求，面板布局符合人体工程学，旋钮操作手感顺滑且定位清晰，适合频繁调节的科研和检测环境。随机不包含电源适配器，使用时无需外接电源，即插即用。产品寿命周期内提供常规维护指导，建议定期清洁触点并检查机械部件状态。2914
Additional Technical Features
The capacitance box utilizes modular decade switching assemblies, with each decimal unit composed of multiple precision capacitors in parallel to create 1-10 steps. The fully shielded construction minimizes stray capacitance effects (residual capacitance ≤80pF). Operating at 50V RMS with optimal accuracy between 800-1000Hz, it features compensated temperature coefficients that limit capacitance variation to within half of basic error when ambient temperature fluctuates within +20℃±5℃. The ergonomic front panel design incorporates smooth-rotating knobs with positive detents, ideal for frequent adjustments in research and testing scenarios. No external power supply is required for operation. Routine maintenance includes periodic contact cleaning and mechanical inspection to ensure prolonged service life. Detailed operating guidelines are provided with the product.72022
