Potentiometer — 500 ohm, linear, horizontal mounting Key benefits - Precise, predictable control: linear taper provides direct proportional change in output as the shaft is rotated, making adjustments intuitive and repeatable. - Space-saving installation: lying-down (horizontal) orientation minimizes profile height for compact panels and PCBs. - Stable performance across environments: rated operating range supports use from -25 to 70 C for many indoor and sheltered outdoor applications. - Low-power, reliable signal source: 500 ohm resistance with a 150 mW power rating is suitable for signal-level circuits and control inputs. What it does and why you need it - Function: acts as an adjustable voltage divider or variable resistance in circuits, allowing you to fine-tune signal levels, setpoints, or user-adjustable controls. - Problem solved: replaces fixed resistors and simplifies calibration tasks, enabling on-device adjustments without rework or component changes. - Standout attribute: the 235 ± 5 degrees rotation range gives a wide, usable sweep for fine adjustment and easy tuning. Key specifications (as supplied) - Item: Potentiometer - Resistance value: 500 ohms - Power rating: 150 mW - Orientation: lying down (horizontal) - Rotation angle: 235 ± 5 degrees - Characteristic: linear - Operating temperature: -25 to 70 C Compatibility and performance notes - Function-compatible with low-power signal and control circuits, analog inputs, and user-adjustable interfaces. - Horizontal mounting is ideal for applications where vertical clearance is limited; check panel or PCB layout for shaft access and mechanical fit. - Linear characteristic makes it suitable for applications that require proportional response rather than logarithmic/audio taper behavior. - Verify the 150 mW power rating against your circuit’s maximum dissipation to ensure safe operation in the intended use. Practical applications (examples) - Instrumentation and test equipment: adjust setpoints, calibrate sensors, or trim reference voltages in bench instruments and measurement devices. - Control panels and user interfaces: provide smooth, proportional control for dimmers, speed controls, and parameter tuning where a compact, low-profile control is required. - Consumer electronics and embedded systems: use as an input device for microcontroller analog channels to allow user-adjustable settings or presets. Installation tips - Confirm orientation and clearance for lying-down mounting; plan for shaft access and any required bezel or panel cutout. - Ensure the circuit’s maximum voltage/current does not exceed the 150 mW dissipation limit of the potentiometer. - For consistent long-term performance, operate within the specified temperature range of -25 to 70 C and avoid exposure to corrosive environments. Specifications recap - Resistance: 500 ohms - Power: 150 mW - Orientation: lying down - Rotation angle: 235 ± 5 degrees - Characteristic: linear - Operating temperature: -25 to 70 C
