RX7/N59十進(jìn)電容箱
產(chǎn)品概述
RX7/N59十進(jìn)電容箱是一款精密的旋鈕式可調(diào)電容設(shè)備,專為需要高精度電容調(diào)節(jié)的電路設(shè)計而開發(fā)。該產(chǎn)品采用十進(jìn)制步進(jìn)調(diào)節(jié)機(jī)制,能夠提供穩(wěn)定且精確的電容值變化,適用于實(shí)驗(yàn)室、科研機(jī)構(gòu)及工業(yè)領(lǐng)域的多種應(yīng)用場景。其核心功能包括作為交流電橋的可變阻抗元件、濾波電路的容抗組件,以及電容表校正的參考器具。產(chǎn)品工作環(huán)境要求為空氣溫度+10℃至+35℃,相對濕度30%~80%,確保在常規(guī)實(shí)驗(yàn)條件下穩(wěn)定運(yùn)行。2710
技術(shù)特性
RX7/N59電容箱的最大容量為11.110μF,最小步進(jìn)值為0.001μF(即1000pF),通過五組十進(jìn)制旋鈕實(shí)現(xiàn)精細(xì)調(diào)節(jié)。各組電容的精度分別為:1μF組±0.5%、0.1μF組±0.5%、0.01μF組±0.65%、0.001μF組±2%。產(chǎn)品采用優(yōu)質(zhì)介質(zhì)材料,在800-1000Hz工作頻率下電介質(zhì)損耗角正切值低于行業(yè)平均水平,其中1μF組損耗值≤2.5×10⁻³。設(shè)備外形尺寸為262×205×130mm,重量約1.8kg,便于實(shí)驗(yàn)室臺面放置和移動。71617
應(yīng)用場景
該電容箱廣泛應(yīng)用于電子工程領(lǐng)域的精密測量與調(diào)試,特別適合作為高頻交流電橋的可變?nèi)菘贡,或用于?gòu)建濾波移相電路。在教育領(lǐng)域,可用于演示電容特性實(shí)驗(yàn)及電路響應(yīng)分析;在工業(yè)生產(chǎn)中,能協(xié)助校準(zhǔn)檢測設(shè)備。其寬范圍可調(diào)特性(0~11.110μF)支持從皮法級到微法級的電容需求,滿足不同場景下對電容精度的多樣化要求。產(chǎn)品采用模塊化設(shè)計,每組電容元件獨(dú)立并聯(lián),通過旋轉(zhuǎn)開關(guān)實(shí)現(xiàn)0-10的步進(jìn)組合。5921
設(shè)計特點(diǎn)
產(chǎn)品采用機(jī)械式旋鈕調(diào)節(jié),每個十進(jìn)制組件包含四個不同容量的精密電容元件,通過鍍金觸點(diǎn)確保接觸可靠性。外殼采用金屬屏蔽結(jié)構(gòu),有效減少外部電磁干擾。內(nèi)部布局優(yōu)化了信號路徑,降低分布電容影響。面板標(biāo)注清晰,包含容量刻度標(biāo)識和旋轉(zhuǎn)方向指示,便于快速操作。起始電容控制在≤110pF范圍內(nèi),用戶可通過校準(zhǔn)消除零位誤差。61822
English Product Description
The RX7/N59 Decade Capacitance Box is a precision rotary-switch adjustable capacitor unit designed for laboratory and industrial applications requiring accurate capacitance variation. This device features five-decade switching with a total range of 0-11.110μF and minimum step increment of 0.001μF (1000pF). The metal-enclosed construction provides electromagnetic shielding while the ergonomic knob design ensures smooth operation.
Key specifications include: 1μF section (±0.5% accuracy), 0.1μF section (±0.5%), 0.01μF section (±0.65%), and 0.001μF section (±2%). The unit operates optimally at 800-1000Hz frequency with low dissipation factor (tanδ≤2.5×10⁻³ for 1μF range). Typical applications include serving as variable reactance in AC bridges, filter network components, and calibration references.
The compact chassis (262×205×130mm) incorporates durable switch contacts and clear range markings. Each decade consists of parallel-connected precision capacitors activated by rotary switches, allowing 0-10 step combinations per section. The design minimizes stray capacitance and maintains stable performance within 10-35℃ temperature range at 30-80% relative humidity. 571016
