" Resistor Color Code Calculator "

Axial lead type color ring resistors , this type of resistor can determine the resistance value and tolerance of the resistor through the number and color of the color ring ring on the surface. Finding these types of resistors is basically a daily routine for us engineers, whether repairing an old PCBA or prototyping a new project. If you have this type of resistor on hand and need to buy new ones, what do you typically do? DigiKey offers an online conversion calculator. It helps to quickly find these resistor color code information.

This calculator offers all 3 types of ribbon systems (4-ring, 5-ring and 6-ring). You just select the color of the color ring and the resistance value, tolerance or PPM value is displayed. Or conversely, you enter the resistor value and see what color it belongs to.

4 color rings

5 color rings

6 color rings

After entering the required information, click Search Directory to view the search results.

Resistor values and tolerances are shown at a glance, along with search results. You can select the resistor you need from the list below to view details or purchase a resistor. For resistor product details and specifications, press the button to send them. It's convenient and fast.

Other ways to find resistor color code information

Have you ever encountered a problem where the color code or resistance value of a resistor cannot be recognized?

Below is a real-life example from our technical forum . The customer has a resistor from the 1950s, but does not know other information about the resistor, such as resistance value, tolerance or PPM value. Guests had no choice but to ask on our technical forums and try to find answers.

Our engineers quickly provide the most appropriate advice and answers.
