Product Description
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 protective layer, these resistors offer excellent heat and weather resistance. They are compatible with reflow and wave soldering processes. The terminal lead-free products comply with EU RoHS directives, with lead glass contained in electrodes, resistance film layers, and glass being exempt. AEC-Q200 data is available for most models (excluding 1F). These resistors are suitable for a wide range of applications including automotive, medical, and aerospace equipment where safety and reliability are paramount.
