Key Features of 100K Preset Potentiometer - (Pack of 5)
- 100K Ohm Resistance: Provides a wide adjustment range suitable for signal conditioning, gain setting, and threshold tuning.
- Compact Preset Design: Small-footprint trimpot mounts directly onto breadboards and PCBs, saving space in tight layouts.
- Screwdriver Adjustable: Top-adjust slot allows precise, stable resistance setting that won't drift during normal operation.
- 3-Pin Through-Hole: Standard pin configuration (Pin 1, Wiper, Pin 3) for easy integration into any circuit.
- Linear Taper: Resistance changes proportionally with rotation for predictable, repeatable adjustments.
- Breadboard & PCB Friendly: 2.54mm-compatible pin spacing fits standard prototyping boards and custom PCBs.
- Pack of 5: Multiple units for multi-channel calibration, spare replacements, or classroom use.
- 100% authentic components from trusted suppliers - no counterfeits
- Consistent quality across all 5 pieces for reliable circuit performance
- Affordable pack pricing - great value for prototyping and education
Perfect For
- Arduino Analog Input Calibration: Use the trimpot as a voltage divider to provide a tunable analog reference voltage to an Arduino ADC pin - perfect for setting sensor thresholds or testing analogRead() values.
- LED Brightness Control: Place the preset in series with a current-limiting resistor to fine-tune LED brightness during prototyping without swapping fixed resistors.
- Audio Amplifier Gain Setting: Integrate into the feedback loop of an op-amp circuit (e.g., LM386) to precisely set amplifier gain during assembly.
How a Preset Potentiometer Works
A preset potentiometer (trimpot) is a three-terminal variable resistor designed for "set and forget" adjustments. A resistive track is connected between two outer pins, and a movable wiper (center pin) slides along the track when turned with a screwdriver. By rotating the adjustment screw, you change the wiper's position, which varies the resistance between the wiper and each outer pin. This allows you to precisely set a voltage divider ratio, calibrate a sensor threshold, or fine-tune an amplifier's gain without needing a full-size panel-mount potentiometer. Unlike user-facing pots, presets are intended to be adjusted during assembly or calibration and then left in place.
Pinout & Wiring Guide
| Pin | Label | Description |
| 1 | Terminal A | One end of the resistive track - connect to VCC or signal source |
| 2 | Wiper (W) | Variable output - connect to the circuit input or ADC pin |
| 3 | Terminal B | Other end of the resistive track - connect to GND or reference |
As a Voltage Divider: Connect Pin 1 to VCC, Pin 3 to GND, and read the adjustable voltage from Pin 2 (Wiper). Turning the screw sweeps the output from 0V to VCC.
As a Variable Resistor (Rheostat): Connect Pin 2 (Wiper) to one of the outer pins (e.g., Pin 1) and use Pin 2 and Pin 3 as a two-terminal variable resistor with range 0-100KOhm.
