Practical electronics calculators for real-world design
Fast engineering tools for component selection, tolerance analysis, worst-case calculations, and everyday circuit design.
Engineering Calculators
Voltage DividerDesign and analyze voltage dividers, including tolerances, resistor power, and worst-case results.
Parallel ResistorFind equivalent resistance and explore useful resistor combinations.
Resistor Color CodeConvert resistor color bands to values—or values back to color bands.
SMD Resistor CodeDecode and generate 3-digit, 4-digit, and EIA-96 resistor markings.
SMD Capacitor CodeDecode and generate 3-digit, 4-digit, and EIA-198 capacitor markings.More engineering tools coming soon
