Product Description

WH148 Carbon Film Potentiometer 3PIN B1K

SingleGang Linear Potentiometer for Very LowImpedance Mono Control Applications

The WH148 B1K is a singlegang (3pin) carbon film rotary potentiometer with a 1K 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 very lowimpedance mono audio circuits, headphone amplifiers, currentsensing applications, and precision singlechannel controls where very low resistance values are required.

Resistance value: 1K 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 50V maximum operating voltage (B-curve variants at 1K)

For headphone amplifiers, this 1K pot provides excellent current handling and low noise
For current-sensing circuits, use this pot as a variable shunt resistor
For voltage divider applications, the 1K value provides excellent current capacity
Identify pin functions: pin 1 input/high, pin 2 wiper/output, pin 3 = ground/low
This very low resistance (1K) is preferred for highcurrent and very lowimpedance applications
Potentiometer is also known as the RV16AF series in some markets

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
