Product Overview
The RK73Z series offers rectangular flat chip jumper resistors designed for high reliability and performance. These components feature a small and lightweight design with excellent heat and weather resistance due to their metal glaze thick film resistive element. The triple-layer electrode structure ensures stability and high reliability, making them suitable for automatic mounting machines and compatible with both flow and reflow soldering. Terminations are lead-free and RoHS compliant. These resistors are ideal for applications requiring high precision and durability, including automotive, medical, and aerospace equipment, with AEC-Q200 qualification available for most types.
