Product Description

WH148 Carbon Film Potentiometer 3PIN B50K

Single-Gang Linear Potentiometer for Versatile Mono Control Applications

The WH148 B50K is a singlegang (3pin) carbon film rotary potentiometer with a 50K ohm resistance and a linear (Btaper) response curve. This compact 16mm diameter component features one independent potentiometer in a single housing, making it ideal for generalpurpose mono controls, audio circuits, bias adjustments, and precision single-channel applications where medium resistance values are required.

Resistance value: 50K ohms ±20% tolerance
Linear (Bcurve) taper resistance changes proportionally with rotation angle
Single-gang design with 3 pins (input, wiper, ground)
Total mechanical rotation: 300° ±5°
Ensure proper wiring identification - pin 1 (input/high), pin 2 (wiper/output), pin 3 (ground/low)
Do not exceed 200V maximum operating voltage (B-curve variants)

For Arduino projects, use this 50K pot for stable analog readings - connect wiper to analog input, outer pins to GND and 5V/3.3V
For mono audio applications, this 50K value offers a good balance between noise and signal integrity
For voltage divider applications, the 50K value provides moderate current handling capacity
Identify pin functions: pin 1 input/high, pin 2 wiper/output, pin 3 = ground/low
This 50K value is commonly used in general-purpose audio and instrument circuits
Potentiometer is also known as the RV16AF series in some markets

Avoid exceeding 0.1W power rating to prevent overheating

Avoid overtightening the mounting nut- as this can damage the shaft or housing
