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. Featuring a metal glaze thick film for excellent heat and weather resistance, these resistors are suitable for reflow and wave soldering. They are RoHS compliant with lead-free terminals, and AEC-Q200 data is available for most models. These resistors are ideal for demanding applications including automotive, medical, and aerospace equipment.

Product Attributes

  • Brand: RK73B
  • Material: Metal Glaze Thick Film, Ceramic Substrate
  • Appearance Color: Black
  • Certifications: EU RoHS compliant (excluding lead glass in electrodes and resistive film), AEC-Q200 data available (except 1F)
