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 TCR of 10010-6/K. These resistors are compatible with reflow and flow soldering, and lead-free termination products meet EU-RoHS requirements. They are AEC-Q200 qualified (excluding 1H type).
