Thick Film Chip Resistors KOA RK73B1ETTP104J Suitable for Automotive Medical and Aerospace Applications
THICK FILM CHIP RESISTORS RK73B
The RK73B series offers a robust lineup of thick film chip resistors, available in sizes from 0402 to 6432. Featuring a protective film made of metal glaze thick film, 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; lead glass contained in electrodes, resistance film layers, and glass are 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 reliability and performance are critical.
