Product Overview

The RK73H series of Flat Chip Resistors (Precision Grade) are designed for high reliability and stability, suitable for demanding applications such as automotive, medical, and aerospace equipment. They feature a small size, light weight, excellent heat and weather resistance due to a metal glaze thick film, and a stable triple-layer electrode structure. These resistors are compatible with automated mounting processes and both flow and reflow soldering. They meet EU-RoHS requirements for lead-free terminations, with exceptions for lead glass in the electrode, resistor element, and glass.
