Product Overview
The KOA RK73H series are thick film (precision grade) flat chip resistors designed for a wide range of applications, including automotive, medical, and aerospace equipment. They offer small size, light weight, excellent heat and weather resistance due to their metal glaze thick film construction, and high stability and reliability with a triple-layer electrode structure. These resistors are compatible with automatic mounters and suitable for both flow and reflow soldering. They feature lead-free terminations, complying with EU-RoHS requirements, with exemptions for lead glass in the electrode, resistor element, and glass. AEC-Q200 qualified data is available for most types.
