Product Description
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. They offer small size, light weight, and high stability and reliability due to their triple-layer electrode structure. These resistors are compatible with various automatic mounting machines for taping and suitable for both flow and reflow soldering. Products with lead-free terminations meet EU-RoHS requirements, with exemptions for lead glass in electrode, resistor element, and glass. Many types are AEC-Q200 qualified.
