RX7/4十進電容箱(多值可調)
RX7/4十進電容箱產品介紹（中文）
RX7/4十進電容箱是一種精密的旋鈕式可調電容設備，適用于交流電路中作為可變標準電容器或電橋的可變橋臂。該產品采用十進制設計，容量范圍為0-1μF，通過(0-10)×0.1μF的組合方式實現(xiàn)精確調節(jié)，最小步進值為0.1μF。在10KHz以下的交流電路中，可作為精密電容元件使用，廣泛應用于濾波、振蕩電路以及阻抗匹配等場景。產品采用優(yōu)質材料制造，具有損耗角正切值小的特點，在1μF容量時損耗角正切值小于0.005。工作頻率范圍覆蓋50Hz至1500Hz，額定工作電壓為250V交流有效值，直流耐壓可達630V。外形尺寸為448W174D133H毫米，重量約4.7公斤，便于實驗室和工業(yè)現(xiàn)場使用。135
RX7/4 Decade Capacitance Box Product Introduction (English)
The RX7/4 decade capacitance box is a precision rotary-switch adjustable capacitor device designed for use in AC circuits as a variable standard capacitor or bridge arm. With a capacitance range of 0-1μF achieved through (0-10)×0.1μF combination, it provides precise adjustment with minimum step value of 0.1μF. This instrument serves as an accurate capacitive component in AC circuits below 10KHz, widely applied in filtering, oscillation circuits and impedance matching applications. Manufactured with high-quality materials, it features low loss tangent (tanδ <0.005 at 1μF). The operational frequency ranges from 50Hz to 1500Hz, with rated working voltage of 250V AC RMS and DC withstand voltage up to 630V. The compact dimensions of 448W174D133H mm and 4.7kg weight make it suitable for both laboratory and industrial applications.11220
產品特點與優(yōu)勢（中文）
該電容箱采用機械式十進制旋鈕設計，操作簡便直觀，每個檔位均可獨立調節(jié)，實現(xiàn)電容值的線性變化。產品具有較高的穩(wěn)定性，在環(huán)境溫度20±5℃、相對濕度30%-80%條件下能保持良好性能。內部采用特殊工藝處理的電容元件，具備自恢復特性，即使遭遇瞬間高壓擊穿也不會永久損壞。電容箱的接觸電阻小，可減少測量誤差，適用于高校電工實驗、科研院所計量測試等場景。產品提供多種容量規(guī)格可選，用戶可根據(jù)實際需求選擇不同型號，滿足從精密測量到常規(guī)實驗的各種要求。161822
Features and Advantages (English)
Featuring mechanical decade knob design, this capacitance box offers intuitive operation with independent adjustment for each range, enabling linear capacitance variation. It demonstrates excellent stability, maintaining reliable performance under ambient temperature of 20±5℃ and relative humidity of 30%-80%. The specially processed capacitor elements inside possess self-recovery characteristics, preventing permanent damage from transient voltage breakdown. With low contact resistance to minimize measurement errors, it s ideal for electrical engineering experiments in universities and metrological tests in research institutes. Multiple capacitance specifications are available to meet diverse requirements from precision measurement to routine experiments.131723
