Product Description

WH148 Carbon Film Potentiometer 3PIN 15MM 100K

SingleGang Linear Potentiometer with 15mm Shaft for HighImpedance Control Applications

The WH148 B100K is a singlegang (3pin) carbon film rotary potentiometer featuring a 100K ohm resistance, a linear (Btaper) response curve, and a 15mm shaft length. This compact 16mm diameter component is ideal for highimpedance audio circuits, guitar tone controls, tube amplifiers, and precision single-channel applications.

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
