技術(shù)特性
GX9/4H的電感可調(diào)范圍為(0～10)×100mH，最小步進(jìn)為100mH，最大電感可達(dá)1000mH。工作頻率范圍覆蓋30kHz至50kHz，額定工作電流為0.5A，建議在1/2最大電流以下長(zhǎng)期工作以確保穩(wěn)定性。產(chǎn)品采用ABS塑料外殼封裝，面板設(shè)計(jì)簡(jiǎn)潔，轉(zhuǎn)換開關(guān)與接線端鈕布局合理，操作便捷。電感線圈采用高頻高Q材料繞制，殘余電感≤5μH，在+5℃～+35℃環(huán)境溫度下性能穩(wěn)定。179
應(yīng)用領(lǐng)域
本產(chǎn)品主要應(yīng)用于300Hz～100kHz頻率范圍內(nèi)的交流電路，可作為自感可變標(biāo)準(zhǔn)器使用。在實(shí)驗(yàn)室環(huán)境中，常用于構(gòu)建精密測(cè)量電橋的橋臂元件，或作為振蕩器、濾波器的核心調(diào)諧組件。其高頻特性使其特別適合射頻電路調(diào)試、通信設(shè)備研發(fā)等對(duì)信號(hào)純度要求較高的場(chǎng)合。此外，該電感箱還可用于電子教學(xué)演示，幫助學(xué)生理解電感參數(shù)對(duì)電路特性的影響。29
使用注意事項(xiàng)
使用時(shí)應(yīng)確保環(huán)境溫度在+5℃～+35℃之間，相對(duì)濕度30%～80%。安裝位置需遠(yuǎn)離金屬物體以避免電感量精度受影響。連續(xù)工作時(shí)間建議不超過2小時(shí)，長(zhǎng)期工作時(shí)應(yīng)控制電流不超過額定值的50%。存放時(shí)應(yīng)置于干燥通風(fēng)環(huán)境中，避免腐蝕性氣體侵蝕。產(chǎn)品采用十進(jìn)制開關(guān)調(diào)節(jié)，轉(zhuǎn)換時(shí)需確保檔位到位以避免接觸電阻引入誤差。914
Product Overview
The GX9/4H High-Frequency High-Q Decade Inductance Box is a precision adjustable inductor designed for high-frequency circuits. With its decade stepping mechanism, it provides stable and accurate inductance value variation. Ideal for laboratories, research institutions, and electronic engineering applications, this unit can be used to construct bridge arms, tuning circuits, oscillators, and filters. Its outstanding feature lies in excellent high-frequency performance and high quality factor (Q), maintaining stable electrical characteristics across broad frequency ranges. 12
Technical Specifications
The GX9/4H offers adjustable inductance range of (0-10)×100mH with minimum step of 100mH and maximum inductance of 1000mH. Operating frequency ranges from 30kHz to 50kHz, with rated current of 0.5A (recommended working below half of maximum current for prolonged stability). The ABS plastic enclosure houses specially wound high-Q coils with residual inductance ≤5μH, showing consistent performance within +5℃～+35℃ ambient temperature. The front panel features clearly marked terminals and rotary switch for intuitive operation. 7914
Typical Applications
This inductance box serves as variable standard inductor in AC circuits from 300Hz to 100kHz. Common applications include precision measurement bridges, oscillator tank circuits, and RF filter networks in laboratory settings. Its high-frequency characteristics make it particularly suitable for RF circuit debugging and communication equipment development requiring high signal purity. Additionally, it serves as effective educational tool for demonstrating inductance parameters impact on circuit behavior in electronics training. 29
Operational Guidance
Operate within +5℃～+35℃ environment with 30%-80% relative humidity. Maintain sufficient distance from metal objects to prevent inductance deviation. Limit continuous operation to 2 hours maximum, keeping current below 50% of rated value for extended use. Store in dry, ventilated area away from corrosive substances. When adjusting decade switches, ensure positive engagement to minimize contact resistance effects. 914
