Product Overview
The RK73H series of Flat Chip Resistors are precision-grade, thick-film resistors designed for a wide range of applications, including automotive, medical, and aerospace equipment. They offer small size, light weight, excellent heat and weather resistance due to their metal glaze thick film construction. The triple-layer electrode structure ensures high stability and reliability. These resistors are compatible with automatic mounters and suitable for both flow and reflow soldering. They comply with EU-RoHS requirements for lead-free terminations.
