RWR74S49R9BPB12 - Wirewound Resistors

Download the RWR74S49R9BPB12 datasheet PDF. This datasheet also covers the RWR71 variant, as both devices belong to the same wirewound resistors family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • High temperature silicone coated.
  • Complete welded construction.
  • Qualified to MIL-PRF-39007.
  • Available in non-inductive styles (type N) with Aryton-Perry winding for lowest reactive components.
  • “S” level failure rate available Note.
  • “Terminal Wire and Winding” type “W” and “Z” are not listed below but are available upon request. Please reference MIL-PRF-39007 QPL for approved “failure rate” and “resistance tolerance/ranges”.
