3362P-1-201 – BOURNS

Overview

The Bourns 3362P-1-201 is a single-turn cermet trimmer potentiometer designed for precise resistance adjustments in through-hole PCB applications. Its 200-ohm nominal resistance and 500 mW power rating make it suitable for signal conditioning and calibration circuits. A critical design consideration for this component is managing thermal drift; while its 100 PPM/°C temperature coefficient offers reasonable stability, designers must ensure adequate heatsinking or operate well below its maximum power rating in environments with significant temperature fluctuations to maintain calibration accuracy and prevent premature component degradation, a common trade-off in cost-effective trimming solutions.
