THICK FILM CHIP RESISTORS RK73B
The RK73B series of thick film chip resistors are designed for a wide range of applications with a robust product lineup from 0402 to 6432 sizes. Featuring a metal glaze thick film protective coating, 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 exemptions for lead glass in electrodes, resistive film layers, and ceramics. AEC-Q200 data is available for most models (excluding 1F). These resistors are suitable for automotive, medical, and aerospace equipment, as well as other applications where safety and significant loss are concerns.
