Last Updated: September 2026
1. Acceptance of Terms
By accessing or using CircuitCalc (circuitcalc.dev), you agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use the website.
2. Engineering & Safety Disclaimer
All calculations, formulas, tables, and component ratings provided on this website are intended solely for educational, reference, and rapid estimation purposes. While we strive for absolute mathematical precision and adhere to recognized standards such as IPC-2221, real-world electrical behavior depends on ambient environmental factors, component manufacturing tolerances, PCB stackups, and thermal dissipation paths.
Always verify critical circuit designs against official manufacturer datasheets, regulatory compliance codes (e.g., UL, CE, NEC), and bench validation measurements before committing to production fabrication or life-critical applications.
3. Permitted Usage
CircuitCalc is free to use for hobbyist, academic, personal, and professional engineering projects. You are welcome to bookmark, link to, or share results and calculations from this site freely. Automated scraping or framing without attribution is prohibited.
4. Limitation of Liability
In no event shall CircuitCalc, Dgen Technologies, or its operators be held liable for any direct, indirect, incidental, or consequential damages, component damage, thermal events, or hardware failures resulting from the use of or inability to use these calculation tools.
