Product Description

WH148 Carbon Film Potentiometer 6PIN B2K

DualGang Linear Potentiometer for LowImpedance Precision Control

The WH148 B2K is a dualgang (6pin) carbon film rotary potentiometer with a 2K 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 lowimpedance audio circuits, headphone amplifiers, and precision dualchannel adjustments where lower resistance values are required.

Resistance value: 2K 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 50V maximum operating voltage (B-curve variants at 2K)

For headphone amplifiers, use this 2K pot for low-Z volume control
For battery-powered devices, the lower resistance ensures lower noise and better signal integrity
For voltage divider applications, the 2K value provides good current handling capability
Identify pin functions: for each 3-pin gang, pin 1 input/high, pin 2 wiper/output, pin 3 = ground/low
Potentiometer is also known as the RV16AF series in some markets
This low resistance (2K) is preferred for lowimpedance headphone outputs and linelevel signals

Avoid exceeding 0.25W power rating to prevent overheating

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

Avoid use in highimpedance circuits- as the low resistance may load the signal source excessively
