Product Description
Product Overview
The KOA RK73H series are rectangular flat chip resistors (precision grade) designed for high reliability and stability. They feature a small size, light weight, and excellent heat and weather resistance due to their metal glaze thick film construction. The triple-layer electrode structure ensures high reliability. These resistors are suitable for automated mounting processes and both flow and reflow soldering. They are RoHS compliant, with lead-free terminations. Certain series are AEC-Q200 qualified.
