Product Overview
The RK73H series are precision-grade flat chip resistors featuring a thick film metal glaze resistive element for excellent heat and weather resistance. Their triple-layer electrode structure ensures high stability and reliability. These resistors are designed for automated mounting processes, supporting various taping methods and both flow and reflow soldering. Products with lead-free terminations comply with EU-RoHS requirements, with exemptions for lead glass in electrode, resistor element, and glass. Many models are AEC-Q200 qualified, making them suitable for demanding applications.
