Resistor dissipation
✕ errorWhat it checks
The DC solver knows the real current through every resistor, therefore the real power. Checked against the declared rating, or the footprint's typical rating (an 0603 is a 0.1 W part), or flagged past a generic ¼ W when neither is known.
Why it matters
A resistor at 10× its rating doesn't drift — it discolors, smokes, and opens. At 70–100% it quietly cooks itself and its neighbors and drifts out of tolerance. P = I²R has no mercy and no warning period.
How to fix it
Bigger package (0805 → 1206 → through-hole), a properly rated power resistor, or revisit why that much current crosses that resistance in the first place — high dissipation in a resistor is often a topology smell.
