Potentiometer single turn 5 kΩ 125 mW, model EB383698432

Single-turn potentiometer EB383698432 offers a 5 kΩ resistance value with a 125 mW power rating. This compact, through-hole component is intended for precise manual adjustment of voltage or signal levels in low-power electronic circuits. Its single-turn design provides predictable linear (or audio) taper performance for trimming and tuning tasks in instrument panels, audio equipment, and control boards where space is limited and fine adjustment is required.

Advantages

The potentiometer provides stable resistance over its adjustment range and reliable mechanical feel for repeated manual operation. Its compact through-hole package facilitates secure PCB mounting and straightforward replacement in existing designs. With a 5 kΩ nominal resistance and a 125 mW power rating, it is optimized for low-power trimming applications, offering consistent electrical behavior and minimal thermal drift when used within specified limits.

Suitable for

• Trimming gain or bias in analog audio circuits
• Adjusting reference voltages on control boards
• Fine-tuning sensor signal levels in measuring instruments
• Calibration and user adjustments on compact instrument panels

Key specifications

• Resistance: 5 kΩ nominal
• Power rating: 125 mW
• Configuration: single-turn potentiometer
• Mounting style: through-hole
• Taper: linear or audio (dependent on variant)
• Typical use: low-power signal trimming and tuning
• Package: compact PCB-mount form factor

How to use

Mount the potentiometer in the designated through-hole footprint on the printed circuit board and solder the pins according to the circuit schematic. Connect the outer terminals to the ends of the resistive element and the middle terminal to the wiper for variable output. Adjust the shaft slowly while measuring the circuit point to achieve the desired voltage or signal level. Ensure the device is not exposed to currents or voltages that would exceed the 125 mW dissipation rating to prevent overheating and long-term drift.

Usage recommendations

Use the potentiometer for low-power adjustment tasks; avoid applying high currents. For stable long-term performance, limit mechanical stress on the shaft, avoid frequent full-rotation cycles beyond intended use, and keep the component within recommended ambient temperature ranges. If the required power dissipation or tolerance is greater than this component provides, choose a higher-power or more precise alternative.
