THICK FILM CHIP RESISTORS RK73B
The RK73B series of thick film chip resistors offers a robust product lineup from 0402 to 6432 sizes. Featuring a metal glaze thick film protective layer, these resistors exhibit 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 in electrodes, resistive 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, especially where safety and reliability are paramount.
