3296X-001-502 – BOURNS

Overview

The Bourns 3296X-1-502LF is a high-precision 5 kΩ cermet trimmer potentiometer designed for critical adjustment applications. Its 0.5W power rating and ±100ppm/°C temperature coefficient ensure stable resistance over varying environmental conditions, a crucial factor in maintaining calibration accuracy in sensitive circuits. A common design challenge with such high-resolution trimmers is the potential for mechanical drift during soldering or vibration; however, the 3296X series’ sealed construction mitigates this risk, providing robust long-term reliability for applications demanding consistent performance.
