FMT40 General-Purpose Decade Inductance Box Product Introduction
The FMT40 General-Purpose Decade Inductance Box is a precision adjustment device specifically designed for electronic circuit experimentation, electromagnetic measurement, and signal debugging. Featuring a modular decimal structure design, this product enables flexible and stable inductance value adjustment through optimized combinations of independent coil groups, making it suitable for various applications including scientific research institutions, educational laboratories, and industrial equipment calibration.
Constructed with high-stability alloy magnetic cores and oxidation-resistant enameled wire windings, the device achieves precise stepwise inductance adjustment via mechanical rotary switches. With an adjustable range spanning from 1μH to 100mH and a minimum stepping unit of 1μH, it fulfills requirements for basic circuit matching and filter parameter calibration. The front panel incorporates wear-resistant engineering plastic with anti-static coating, complemented by a dual-color calibrated dial for clear parameter visualization.
The FMT40 implements layered shielding technology to effectively suppress external electromagnetic interference, while silver alloy multi-point contacts ensure long-term connection stability. Its unique thermal dissipation channels combined with low-loss winding configuration maintain optimal temperature characteristics during continuous operation. The unit supports series/parallel mode switching, allowing extended adjustment range through combined connections.
Ideal for electronic laboratory component simulation, educational circuit demonstration, and communication equipment impedance matching, the compact benchtop design balances portability with operational efficiency. All adjustment units are equipped with mechanical locking mechanisms to prevent accidental parameter changes. The vibration-damping base and tri-directional non-slip pads ensure stable performance across diverse working environments.
