Product Description

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, excellent heat and weather resistance due to their metal glaze thick film construction, and a stable triple-layer electrode structure. These resistors are suitable for automated mounting and reflow/wave soldering processes. They are RoHS compliant, with lead-free terminations, and some models are AEC-Q200 qualified. Applications include automotive, medical, and aerospace equipment where human safety or significant loss is a concern.
