Product Description

WH148 Carbon Film Potentiometer 3PIN B100K

SingleGang Linear Potentiometer for HighImpedance Mono Control Applications

The WH148 B100K is a singlegang (3pin) carbon film rotary potentiometer with a 100K 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 highimpedance mono audio circuits, guitar tone controls, tube amplifier adjustments, and precision single-channel applications where high resistance values are required.

Resistance value: 100K 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 200V maximum operating voltage (B-curve variants)

For guitar tone control, this 100K pot works well with high-impedance pickups and is a popular choice for many instruments
For Arduino projects, connect wiper to analog input, outer pins to GND and 5V/3.3V - this value offers good stability
For high-impedance voltage dividers, the 100K value provides excellent performance with low power consumption
Identify pin functions: pin 1 input/high, pin 2 wiper/output, pin 3 = ground/low
This 100K value is widely used in guitar, audio, and general-purpose electronics
Potentiometer is also known as the RV16AF series in some markets

Avoid exceeding 0.063W power rating to prevent overheating

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