Product Overview
The RK73H series of Flat Chip Resistors (Precision Grade) are designed for high reliability and performance in demanding applications. Featuring a small size, light weight, and excellent heat and weather resistance due to their metal glaze thick film construction, these resistors offer high stability with a triple-layer electrode structure. They are compatible with automated mounting processes and various soldering methods, including flow and reflow. Terminations are lead-free, complying with EU-RoHS requirements (excluding lead glass in the electrode, resistor element, and glass). AEC-Q200 qualified data is available for most models.
