Product Description
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, lightweight form factor with 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 automated mounting processes and suitable for both flow and reflow soldering. Terminations are lead-free, complying with EU-RoHS requirements. Certain series are AEC-Q200 qualified.
