Carlsbad Potentiometers MH22B-3 Rotary Potentiometer

Carlsbad Potentiometers MH22B-3 Rotary Potentiometer (MH22B-3-10K) is a 10 kΩ, three-turn precision potentiometer manufactured by ETI Systems as part of the MH22B family, described as a hybrid multi-turn, wire-wound device. It delivers three full turns of resistance travel with a 1 W power rating and a linear taper, providing proportional resistance changes as the shaft rotates for fine adjustment in tight spaces. This combination makes it well suited for calibration and adjustment tasks in instrumentation and test equipment where stable, repeatable resistance steps are required. The MH22B-3-10K designation identifies the 10 kΩ variant of the MH22B-3 family, aligning with ETI Systems’ datasheets that specify 3-turn operation, a 10 kΩ nominal resistance, and a linear taper for predictable behavior.
