3150W105P – TE CONNECTIVITY

Overview

The TE Connectivity 3150W105P is a surface-mount trimmer potentiometer designed for precise resistance adjustment in compact electronic assemblies. Its primary function is to provide a variable resistance element, typically used for calibration or fine-tuning circuit parameters. A critical consideration in its application is the trade-off between adjustment resolution and long-term stability; while offering fine control, the wiper contact can be susceptible to environmental contamination, necessitating careful enclosure design to maintain its calibrated setting over time. This 1MΩ unit is integral for applications demanding accurate, repeatable resistance settings.
