KOA RK73H Flat Chip Resistors (Precision Grade)
The KOA RK73H series offers high-precision flat chip resistors designed for demanding applications. These resistors feature a 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. They are compatible with various automatic mounters and soldering methods, including reflow and wave soldering. Terminations are lead-free and comply with EU-RoHS requirements, with exceptions for lead glass in the electrode, resistor element, and glass.
