Product Overview
The RK73H series offers high-precision flat chip resistors with a thick film construction. These resistors are designed for reliability and stability, featuring a triple-layer electrode structure and excellent heat and weather resistance due to their metal glaze thick film. They are suitable for various automatic mounting processes and soldering methods, including reflow and wave soldering. The products comply with EU RoHS requirements for lead-free terminations. They are qualified for AEC-Q200 (except for the 1F type), making them suitable for demanding applications.
