Product Overview
The RK73H series of Flat Chip Resistors are precision-grade, thick-film resistors designed for demanding 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 high stability and reliability. These resistors are suitable for automatic mounters and compatible with both flow and reflow soldering. They feature lead-free terminations and meet EU-RoHS requirements, with exceptions for lead glass in the electrode, resistor element, and glass. AEC-Q200 qualified data is available for most types.
