The B20K 20K Ohm Linear Taper Rotary Potentiometer (WH148 series) is a compact 3-pin variable resistor used to manually adjust voltage, volume, or signal levels in electronic circuits. Its knurled 6mm shaft accepts a wide range of control knobs, making it a popular choice for DIY audio, lighting, and sensor-calibration projects.
Key Features:
- Resistance: 20KΩ with a B-type linear taper for even, predictable adjustment.
- 3-Pin Terminal: Two outer pins for the resistive track and a centre wiper pin for the output signal.
- Knurled Shaft: 6mm diameter shaft compatible with standard plastic and metal knobs.
- Panel Mount Bushing: Threaded metal bushing allows secure mounting through an enclosure or PCB.
- Power Rating: Rated for 0.05W, suitable for low-power signal and control applications.
- Compact Size: Small footprint fits easily into breadboards, project boxes, and control panels.
Package Includes:
- 1 x B20K 20K Ohm Rotary Potentiometer
