Resistor Color Code Calculator

An app that can do resistor color code calculations

Welcome to our resistor calculator app! Whether you need to determine resistor values through color bands or by directly inputting resistance, our app is designed to make the process easy and efficient.

This app supports resistors for three, four, five, and six band resistors.

- Three Band Resistor: (2 digits, multiplier)

- Four Band Resistor: (2 digits, multiplier, tolerance)

- Five Band Resistor: (3 digits, multiplier, tolerance)

- Six Band Resistor: (3 digits, multiplier, tolerance, temperature coefficient (PPM))

Color-to-Value:

Select the appropriate number of bands and choose colors from the dropdown menus. The calculated values will be displayed under the resistor at the top of the screen. On smaller screens, the dropdowns become scrollable for ease of selection.

Value-to-Color:

Input the desired resistance value while adhering to proper input guidelines. Select the preferred units and, if prompted, specify tolerance and temperature coefficient. The resistor and value will be updated as you continue to update the fields.

Additional Functionalities:

- SMD Resistor Calculator: Our app also includes a Surface-Mount Device (SMD) resistor calculator. Easily convert SMD codes to resistance values via one of the three code standards (3 digit EIA, 4 digit EIA, and EIA-96).

- Sharing Resistors: You can share the resistor you have created either by text or by image! To do this click the 3 vertical dots in the top right and select which method you'd like to share.

All values and calculations are derived from the IEC 60062 standard. More information can be found here:
