Covering Latest Innovations in the Power Engineering Industry

January 21, 2025 – For your convenience, everythingPE (Power Engineering) has created a very nice online app for identifying resistors by their color codes. The color bands on a resistor are used to represent the resistance value, tolerance, and sometimes the temperature coefficient of the resistor. These color bands follow a standardized color code to help identify the resistor's characteristics. The number of color bands on a resistor can vary, but most commonly, you will find resistors with either four or five bands (and sometimes a sixth). Our calculator works with all three varieties.

Band 1 & Band 2: Significant Figures - These bands represent the significant digits of the resistance value. Each color corresponds to a specific number, typically from 0 to 9. The first band represents the tens-place digit, and the second band represents the ones-place digit.

Band 3: Multiplier Band - This band represents the multiplier that should be applied to the significant figures to get the full resistance value. Each color corresponds to a power of 10.

Band 4: The tolerance band indicates the allowable percentage deviation from the nominal resistance value

Band 5: Some resistors, especially precision resistors, include a fifth band to indicate the temperature coefficient. The temperature coefficient band tells you how much the resistor's resistance changes with temperature.

Band 6: The sixth band, if present, provides information about the temperature coefficient or, in some cases, the reliability or failure rate of the resistor.


About everythingPE

everything PE is a new website for the Power Electronics Industry. We keep engineers up to date with the latest news, products, white papers, and upcoming events in the Power Electronics Industry. The everything PE editorial team works hard to ensure that every product release and relevant news story in the Power Electronics sector is added to the site.

The products are ordered by relevance and launch date, so users get to see the latest products that meet their requirements. They can then download the datasheet of a product or request a quotation via everything PE. The quotations are directly routed to the sales contract at the relevant company. In addition to this, it is also, routed to distributors/sales representatives who will be able to quote this product. Our proprietary algorithm sends the inquiry to the relevant distributors/sales representatives based on the location of the user. So if an inquiry is generated from California it will be sent to the manufacturer and their sales reps/distributors for California. Or if an Inquiry is generated from India, will be sent to the manufacturer and their distributor in India.
