Potentiometers What it is: a variable resistor that allows you to adjust voltage or signal level in a circuit with smooth, repeatable control. Key benefits: precise control, low noise, stable over cycles, wide resistance and taper options, durable construction. Compatibility and form: PCB mount, panel mount, and shaft options; rotary or linear (slide); standard shaft sizes (6 mm / 1/4 in); compatible with common soldering and wiring. Specifications you can choose: resistance values from 1 kΩ to 100 kΩ; taper types linear and logarithmic; carbon, cermet, or conductive polymer elements; sealed or unsealed. Size and material: metal shafts, robust housing, grade internal contact. Performance: reliability, tight resistance tolerance, long life. Use cases: 1) Audio equipment: adjust volume, balance, or tone control. 2) Instrumentation: sensor calibration and offset adjustment. 3) Robotics: motor speed or control loop tuning. How to pick: select the appropriate taper for perceptual response, match mounting style to your chassis, choose resistance to set the signal range.
