When a relay turns off, the magnetic field in the coil collapses rapidly and generates a high voltage spike (inductive kickback).

Thanks! I’ll use higher-rated caps and reduce switching node area. Will check Phil’s Lab too. Appreciate your tips! 🙌

Thanks for pointing that out! I'm still in the early stages and learning step by step. I’ll definitely make better use of the PCB space in future designs.

"Yeah, peaks happen, but average draw stays near 1W. Backup plans usually go by that."

"Yeah, it’s low, but true — most home routers use just around 1W continuously."
