Additional Details

The ST-4ETG1K-102 is designed for relatively infrequent adjustments. Always consult the datasheet to determine the appropriate operating voltage and current. The temperature coefficient influences the resistance value over temperature. The exact specifications for the series need to be verified in the datasheet. This series can be sealed. The typical adjustment tool is a small screwdriver.

Careful soldering techniques are necessary to avoid damaging the component. When selecting a trimmer potentiometer, consider the resistance range, tolerance, temperature coefficient, and physical dimensions. Ensure that the potentiometer's power rating is adequate for the intended application. The resistance value will shift with temperature; refer to the datasheet for specifics. Proper handling and storage are essential to maintain the potentiometer's performance.
