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.
