The KOA RK73H series are precision-grade flat chip resistors designed for a wide range of applications, including automotive, medical, and aerospace equipment. These resistors feature a small, lightweight design with excellent heat and weather resistance due to their metal glaze thick film construction. The triple-layer electrode structure ensures high stability and reliability. They are compatible with various automatic mounters and suitable for both flow and reflow soldering. Terminations are lead-free and comply with EU-RoHS requirements, with exceptions for lead glass in the electrode, resistor element, and glass.
