Product Description
THICK FILM CHIP RESISTORS RK73B
The RK73B series offers a robust lineup of thick film chip resistors, available in sizes from 0402 to 6432. Constructed with a metal glaze thick film protective layer, 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 of electrodes, resistive film, and glass is 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 safety and reliability are paramount.
