The sliding varistor is an adjustable resistance element. By moving the sliding contact along the resistance wire connected to the circuit, the effective wire length in the circuit changes, altering resistance and the current in the circuit. Key benefits - High resistance accuracy for precise tuning - High temperature resistance for durability in demanding environments - Low noise during operation for clean signal performance - Stable and reliable operation over time Construction and durability - Wire wound on a tube coated with a non-flammable material - Good heat dissipation to maintain performance - High stability and long service life - The wire wound resistor offers high stability and precision Why you need it - Enables accurate, adjustable resistance for calibration and tuning - Robust design suitable for frequent adjustments in real-world circuits Specifications and performance - Function: adjustable resistance via a sliding contact on a wire wound resistor - Material and construction: wire wound on a non-flammable coated tube - Performance: stable, precise resistance with low noise Applications - Calibration and adjustment in laboratory power supplies and test benches - Adjustable load or current setting in electronic circuits and prototypes - Audio and signal processing circuits requiring precise, tunable resistance Compatibility - Suitable for standard circuits that require adjustable resistance.
