The KOA RK73H series offers high-reliability, precision-grade flat chip resistors designed for demanding applications. These resistors feature a small, lightweight construction 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 automated mounting machines and suitable for both flow and reflow soldering. Terminations are lead-free, complying with EU-RoHS requirements. Many types are AEC-Q200 qualified. Applications include automotive, medical, and aerospace equipment where personal safety or significant loss may be involved, requiring prior consultation with KOA.
