Reliability checklist: require lot sampling, thermal cycling, and reflow verification as standard procurement gates before volume acceptance. Common questions How consistent are the measured specs compared to datasheet specs? Point: Consistency depends on lot and measurement rigor. Evidence: Typical lab results show most elements within ±2% tolerance, with a small fraction near limits; matching often closer than individual tolerance. Explanation: If your application needs tighter matching than observed, specify tighter tolerance parts or sort by element values during incoming test. What practical derating rule should be applied for power per element? Point: Use conservative derating to prevent thermal drift. Evidence: Measure resistance vs. applied power and set operating power at a fraction (commonly 50–75%) of the tested stable region to limit ΔR and avoid thermal runaway. Explanation: Incorporate PCB thermal relief, vias, and distance from hot components to meet that derating in practice. When should designers choose an alternative resistor network? Point: Choose alternatives when measured specs fail system requirements. Evidence: If TCR, matching, noise, or power‑stability measurements exceed your error budget or if post‑stress ΔR rate is unacceptable, move to a part with tighter guaranteed specs. Explanation: Use the documented tests above as a go/no‑go checklist during component selection and procurement.
