Ceramic Substrate Thick Film Chip Resistors KOA RK73B1HTTC114J Ideal for Automotive Medical Aerospace Applications
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 metallic 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 in electrodes, resistive film layers, and glass being exempt. AEC-Q200 data is available for most models (excluding 1F). These resistors are suitable for applications including automotive, medical, and aerospace equipment, as well as other devices where safety or significant loss is a concern.
