The RK73B is a general-purpose thick film chip resistor series featuring 2% and 5% tolerances. It offers a wide lineup from 01005 to 2512 sizes, excellent heat and weather resistance due to its metal glaze thick film construction, and suitability for both flow and reflow soldering. Products with lead-free terminations meet EU RoHS requirements. The series is AEC-Q200 tested for various sizes.
