The VG039NCHXTB153 variable resistor is a single-in-line, surface mount device (SMD) manufactured by Hokuriku. The total resistance range is ±25%, and it is compliant with the Restriction of Hazardous Substances (RoHS) directive. This device is comprised of a variable resistor element, insulator, and a terminal, each requiring precise construction to ensure the necessary electrical performance. The variable resistor is sealed with insulator sealant and allows for today’s demands for high-precision controls. It can be connected to other electronic components, including amplifiers and microcontrollers. The resistance characteristics allow for wide control range, excellent temperature characteristics, and predictable variation in resistance values.
