WH148 Potentiometer 1K 15mm Shaft

The WH148 Potentiometer 1K is a single-turn rotary potentiometer with a 1 kΩ track, three pins and a 15 mm shaft that takes a standard knob. The WH148 is one of the most common panel potentiometers in hobby electronics, and the low 1 kΩ value suits circuits that need a low-impedance adjustable voltage divider, such as reference voltage setting and test circuits.

WH148 Potentiometer 1K Specifications

• Resistance: 1 kΩ between the outer pins
• Series: WH148
• Type: rotary, single turn, about 300° rotation
• Shaft: 15 mm long, 6 mm diameter
• Pins: 3 (two track ends and the wiper)
• Mounting: threaded bushing for panel mounting

WH148 Potentiometer 1K Applications

• Analog input knob for Arduino and ESP32 projects
• Setting reference voltages for comparators and op-amps
• Adjustable voltage dividers on test circuits
• Level and tone controls in low-impedance audio circuits
• Panel controls on DIY power supplies and controllers

What's in the Box

• 1 × WH148 1 kΩ potentiometer, 15 mm shaft

Tip: Connect the outer pins to 5 V and GND and the middle pin (wiper) to an analog input. A 1 kΩ pot across 5 V draws a constant 5 mA, so for battery projects a 10 kΩ pot wastes less power. Do not pass load current through the wiper.
