The 3549S-1AA-201A is a 10-turn precision potentiometer featuring a wirewound element with high rotational life and excellent linearity characteristics. It offers a standard resistance range of 0.100 to 100K ohms with ±3% total resistance tolerance and independent linearity of ±0.2% (maximum practical ±0.1%). The device provides an effective electrical angle of 3600° ±10°, -0° with a mechanical angle of 3600° ±10°, -0° and backlash of 1.0° maximum. With a power rating of 2 watts at +70°C and dielectric withstanding voltage of 1,000 VAC minimum, this potentiometer is well-suited for HMI and MMI applications, instrumentation, and control systems requiring precise analog feedback. The unit features gold-plated solder lugs, optional anti-rotation lug, and is RoHS compliant, making it ideal for demanding industrial and commercial applications.
