Product Description
Product Overview
The SR73 series are low resistance flat chip resistors designed for current detection in power supply and motor circuits. They offer high reliability and performance with a resistance tolerance of 0.5% and a temperature coefficient of 10010-6/K. These resistors are suitable for both reflow and flow soldering and are AEC-Q200 qualified (excluding 1H type). They are widely used in automotive electronics, computers, HDDs, cellular phones, and power supplies.
