Metal glaze thick film resistor KOA RK73H1ETTP1214F with stable resistance and high overload voltage
Product Overview
The RK73H series are thick film precision flat chip resistors designed for high reliability applications. They feature a small, lightweight design with 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 automated mounting and both flow and reflow soldering. They comply with EU-RoHS requirements, with lead-free terminations. Applications include automotive, medical, and aerospace equipment, where failure could lead to serious damage or loss of life.
