Voltage Divider Designer

Find the best standard resistor values (E12/E24) for your desired output voltage.

Design Requirements

Input Voltage (Vin)

Desired Vout

Target Current (mA)

Sets the impedance level of the divider.

Resistor Series

This tool searches through standard resistor series to find the pair that most closely matches your target output voltage while staying near your target current.

Recommended Components

R1 (Top)

1.50 kΩ

R2 (Bottom)

3.00 kΩ

Actual Vout:3.333 V

Voltage Error:1.01%

Actual Current:1.11 mA

Power Dissipation

Ensure your resistors can handle the power: P = V²/R. For a 5V input, total power is 5.5556W.
