Engineering review checklist

  • Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
  • Derate continuous power for ambient temperature and verify pulse or surge capability separately.
  • Match the land pattern, termination finish and current-sense routing to the exact package option.

Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
