Resistor Pair Finder
Find standard resistor combinations that match your target resistance. Ideal for voltage dividers, bias networks, and precision tuning.
Resistor Combination Finder
Enter your target resistance and get the closest E12 resistor pairs for both series and parallel configurations.
Calibrate Your Circuit.
Use the results to fine-tune divider ratios, input impedance, or reference levels. When ready, bring your next design to AOEngineering.
