Product Overview
The RK73H series are thick film precision flat chip resistors designed for high reliability applications. They 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 stability and reliability. These resistors are suitable for automated mounting and both flow and reflow soldering. They comply with EU-RoHS requirements, with lead-free terminations. Applications include automotive, medical, and aerospace equipment, where failure could lead to serious damage or loss of life.
