【English Introduction】
The FMT51 General-Purpose Decade Inductance Box is a precision inductance adjustment device designed for electronic circuit experimentation and educational applications. Featuring a modular decade structure with rotary switch controls, it provides continuously adjustable inductance from 0.1mH to 100mH in 0.1mH increments. The metal alloy shielding enclosure effectively minimizes electromagnetic interference, making it suitable for laboratory environments, research facilities, and electronics enthusiasts engaged in circuit debugging and filter design.
Constructed with high-permeability permalloy cores and oxidation-resistant copper windings, the unit maintains stable inductance values within an operational temperature range of -10°C to +50°C. The front panel incorporates wear-resistant engineering plastic with clearly marked numerical dials and non-slip control knobs, offering tactile feedback for precise range selection. The internal star-type wiring configuration reduces parasitic capacitance effects, ensuring reliable linear performance across 20Hz-5kHz frequency spectrum.
Functionally, three sets of independent terminals allow series or parallel connections to accommodate various circuit configurations. Non-slip rubber feet and an integrated carrying handle enhance both operational stability and portability. For optimal performance, users are advised to maintain ambient humidity below 80%RH and prevent dust accumulation on contact surfaces. With proper maintenance, this device delivers long-term measurement accuracy and operational reliability, serving as a versatile inductance simulation tool for electronic system development.
