【GX9/2H High-Frequency High-Q Decade Inductor Box Product Introduction】
The GX9/2H High-Frequency High-Q Decade Inductor Box is a precision adjustable inductance device specifically designed for high-frequency circuit design and testing applications. Featuring a unique decade step-adjustment mechanism, it provides inductance value adjustment from 0.1μH to 100mH with a minimum step resolution of 0.1μH, making it ideal for precision scenarios such as RF circuit tuning, filter debugging, and resonant circuit matching.
Constructed with low-loss specialty magnetic core materials and multi-layer precision winding technology, the device achieves outstanding Q-factor performance exceeding 200 at 1MHz operating frequency, effectively minimizing energy loss and ensuring signal integrity. The hybrid structure combining high-strength engineering plastics with metal shielding enclosures achieves both lightweight design (total weight <2.5kg) and superior electromagnetic interference protection.
The gold-plated rotary decade switches with dust-resistant design ensure over 100,000 reliable rotations, while clearly marked range scales enable fast and accurate settings. Distributed winding layout significantly reduces parasitic capacitance caused by proximity effects, maintaining inductance linearity error within ±1% across 20kHz-30MHz frequency range. This makes the device particularly suitable for precision applications including load simulation for high-frequency signal generators and impedance matching in wireless communication systems.
Practical enhancements include dual output ports for simultaneous connection to two test systems, along with standard BNC and banana jack interfaces for versatile connectivity. Built-in overload protection circuitry ensures operational safety by automatically disconnecting abnormal currents. For optimal performance, operation within -10℃ to 50℃ temperature range and avoidance of strong magnetic fields are recommended.
