Product Description

WH148 Carbon Film Potentiometer 6PIN B47K

Dual-Gang Linear Potentiometer for Stereo and Precision Control

The WH148 B47K is a dualgang (6pin) carbon film rotary potentiometer with a 47K ohm resistance and a linear (Btaper) response curve[citation:4][citation:11]. 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 volume control, balanced signal processing, and precision dual-channel adjustments*.

Resistance value: 47K ohms ±20% tolerance[citation:11][citation:13]
Linear (Bcurve) taper resistance changes proportionally with rotation angle[citation:4]
Dual-gang design with 6 pins (3 pins per channel)
Total mechanical rotation: 300° ±5°[citation:1][citation:9]
Ensure proper wiring identification - each gang has its own input (pin 1), wiper (pin 2), and ground (pin 3) set[citation:3]
Do not exceed 200V maximum operating voltage (B-curve variants)[citation:1][citation:9]

Package Includes

  1. 1x WH148 6-Pin Dual Potentiometer (B47K)
  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
Use this pot with Arduino by connecting wiper (center pin of each gang) to analog inputs and outer pins to GND and 5V[citation:12]
For volume control, use a logarithmic (Acurve) pot instead this linear (B-curve) pot is better for precision settings[citation:4]
Identify pin functions: for each 3-pin gang, pin 1 input/high, pin 2 wiper/output, pin 3 = ground/low[citation:3]
Potentiometer is also known as the RV16AF series in some markets[citation:12]

Avoid exceeding 0.125W power rating to prevent overheating

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