Product Overview
The RK73H series are thick film precision flat chip resistors designed for high reliability applications. They offer small size, light weight, and excellent heat and weather resistance due to their metal glaze thick film construction. The triple-layer electrode structure ensures stability and reliability. These resistors are suitable for automatic mounters and compatible with both flow and reflow soldering. They feature lead-free terminations meeting EU-RoHS requirements, with exceptions for lead glass in the electrode, resistor element, and glass. Many types are AEC-Q200 qualified. Applications include automotive, medical, and aerospace equipment where failure could cause serious damage.
