Engineering Calculator Disclaimer

All results are estimates. Confirm critical designs with your fabricator, relevant component and material documentation, appropriate analysis and physical validation. The interface does not establish regulatory compliance or certify a board as safe.

Safety-critical and high-voltage work

Clearance and creepage values cannot be determined from voltage alone. This suite deliberately provides a review checklist rather than an unsupported numerical spacing verdict. Medical, automotive, mains and other critical designs need the applicable standards, controlled project assumptions and qualified engineering review.
