THICK FILM CHIP RESISTORS RK73B

The RK73B series thick film chip resistors are designed for a wide range of applications, offering robust performance and a comprehensive product lineup from 0402 to 6432 sizes. Utilizing a metal glaze thick film for the protective coating, these resistors exhibit excellent heat and weather resistance. They are compatible with reflow and wave soldering processes and feature lead-free terminals, complying with EU RoHS directives (lead in glass within electrodes, resistive film, and glass are exempt). AEC-Q200 data is available for most models.
