THICK FILM CHIP RESISTORS RK73B

The RK73B series are thick film chip resistors featuring a robust product lineup from 0402 to 6432 sizes. Constructed with a metal glaze thick film for superior heat and weather resistance, these resistors are suitable for reflow and wave soldering. They are RoHS compliant with lead-free terminals, and lead glass in electrodes, resistance film layers, and glass are exempt from EU RoHS directives. AEC-Q200 data is available for most models.
