Product Description

WH148 Carbon Film Potentiometer 6PIN B20K

Dual-Gang Linear Potentiometer for Stereo and Precision Control Applications

The WH148 B20K is a dualgang (6pin) carbon film rotary potentiometer with a 20K ohm resistance and a linear (Btaper) response curve. This compact 16mm diameter component integrates two independent potentiometers in a single housing, sharing a common shaft for simultaneous, synchronized control making it ideal for stereo audio control, balanced signal processing, dualchannel mixing, and precision dualchannel adjustments.

Resistance value: 20K ohms ±20% tolerance
Linear (Bcurve) taper resistance changes proportionally with rotation angle
Dual-gang design with 6 pins (3 pins per channel)
Total mechanical rotation: 300° ±5°
Ensure proper wiring identification - each gang has its own input (pin 1), wiper (pin 2), and ground (pin 3) set
Do not exceed 200V maximum operating voltage (B-curve variants)

20K Value - Ideal for balanced audio and stereo mixing applications

√ Ready to use - standard 6mm shaft with nut and washer included

√ Low rotational noise - 47mV maximum for clean operation

√ 10,000 cycle durability longlasting performance

Package Includes

  1. 1x WH148 6-Pin Dual Potentiometer (B20K)
  2. 1x Mounting Nut
  3. 1x Washer
For stereo audio applications, connect one gang to the left channel and the other to the right channel
This 20K value provides a good balance between noise performance and signal integrity in stereo circuits
For balanced audio circuits, use both gangs for differential signal control
Identify pin functions: for each 3-pin gang, pin 1 input/high, pin 2 wiper/output, pin 3 = ground/low
This 20K value is commonly used in professional audio and studio equipment
Potentiometer is also known as the RV16AF series in some markets

Avoid exceeding 0.125W power rating to prevent overheating

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