Product Description

WH148 Carbon Film Potentiometer 3PIN B5K

SingleGang Linear Potentiometer for LowImpedance Mono Control Applications

The WH148 B5K is a singlegang (3pin) carbon film rotary potentiometer with a 5K 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 lowimpedance mono audio circuits, headphone amplifiers, sensor adjustments, and precision single-channel applications where lower resistance values are required.

Resistance value: 5K 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 5K)

For headphone amplifiers, use this 5K pot for low-Z volume control with minimal noise
For battery-powered devices, the lower resistance ensures lower noise and better signal integrity
For voltage divider applications, the 5K value provides good current handling capacity
Identify pin functions: pin 1 input/high, pin 2 wiper/output, pin 3 = ground/low
This low resistance (5K) is preferred for lowimpedance headphone outputs and linelevel signals
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

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