Product Description
THICK FILM CHIP RESISTORS RK73B
The RK73B series are thick film chip resistors designed with a metal glaze thick film for excellent heat and weather resistance. They offer a wide product lineup from 0402 to 6432 sizes and are compatible with reflow and wave soldering. These resistors are lead-free compliant with EU RoHS directives (excluding lead glass in electrodes, resistive film, and glass). AEC-Q200 data is available for most models.
