Product Overview
The RK73H series of Flat Chip Resistors (Precision Grade) are designed for high reliability and performance in demanding applications. Featuring a thick film construction with a metal glaze resistive element, these resistors offer excellent heat and weather resistance. Their triple-layer electrode structure ensures stability and trustworthiness. These resistors are suitable for automated mounting processes and various soldering methods, including reflow and wave soldering. They are RoHS compliant with lead-free terminations. AEC-Q200 qualification is available for most models.
