Using our articles and tools
Articles and calculator results are educational starting points. A schematic or calculation alone does not establish that a circuit has been built, tested or certified. Check the article for its stated test conditions and limitations, and consult the manufacturer’s datasheet for the exact component and package you use.
Before building a circuit, check component ratings, polarity, pin assignments and the power source. Calculators simplify real components and do not account for every tolerance, thermal limit or fault condition. Start with low-voltage, current-limited experiments. Mains-connected circuits, high-voltage inverter outputs and high-current batteries require appropriate training, protective equipment and qualified supervision.
