Product Description

Product Overview

The SG73P series is an anti-surge endured pulse power thick film chip resistor designed for high-reliability applications. It offers superior pulse withstanding voltage and high power capabilities compared to RK73B/RK73H series. Available with tolerances down to 0.5%, these resistors are suitable for both reflow and flow solderings. Products with lead-free terminations meet EU RoHS requirements. The series is AEC-Q200 Tested.
