Product Description
THICK FILM CHIP RESISTORS RK73B
The RK73B series offers a robust lineup of thick film chip resistors, available in sizes from 0402 to 6432. These resistors are constructed with a metal glaze thick film protective layer, providing excellent heat and weather resistance. They are compatible with reflow and wave soldering processes and feature lead-free terminals, complying with EU RoHS directives (lead glass in electrodes, resistive film, and glass are exempt). AEC-Q200 data is available for most models.
