3296X-001-103 – BOURNS

Overview

The Bourns 3296X-1-103 is a high-precision cermet trimmer potentiometer designed for critical circuit calibration. Its primary function is to provide a stable, adjustable resistance within a 10 kΩ range, featuring a robust 0.5W power rating and a tight ±10% tolerance. A key engineering consideration for this component is managing thermal drift; while its ±100ppm/°C temperature coefficient is respectable, designers must account for self-heating effects at maximum power to maintain calibration accuracy in high-ambient temperature environments.

Key Features
