Product Overview
The RK73H series of Flat Chip Resistors are precision-grade, thick-film resistors designed for high reliability and stability. They feature a small size, light weight, and excellent heat and weather resistance due to their metal glaze thick film construction. The triple-layer electrode structure ensures high reliability. These resistors are suitable for automatic mounting machines and are compatible with both flow and reflow soldering. They are EU-RoHS compliant, with lead-free terminations. Applications include automotive, medical, and aerospace equipment where failure could result in serious damage or loss of life. AEC-Q200 qualified for most types.
