flat chip jumper resistors KOA RK73Z1HTTC with triple layer electrode structure and RoHS compliance
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.
