CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product
reliability and result in failures not covered by warranty.
NOTES:
4. _JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. For _JC, the “case temp” location is taken at the package top center.
Potentiometer Specifications V_CC = full range. Boldface limits apply across the operating temperature range, -40°C to +85°C
(Industrial) and 0°C to +70°C (Commercial).
