Resistor color table

An easy to use table to work with resistors color code

Downloadable PDF

This resistor color code table can viewed online as this web page, but can also be downloaded as a PDF document that can be printed and easly used on your workbench. The document is still usable even if viewed in black or white, and this is the case of some printers and the majority of ebook readers.

Some notes

To remember the color sequence, somebody prefers to learn by heart the following sentence and then look at the initials of each word:
Bad beer rots our young guts but vodka goes well - get some now.

In order to read the color sequence from the body of the resistor in the correct direction consider the following notes.
A gold or a silver band cannot be at the beginning; If some bands are grouped together, keep this group on the left and start with it; only some colors represent tolerance, so look at the possible tolerance band (4th if bands ar 4 or 5th if bands are 5 or 6) first; if bands are 6 consider that also the 6th band can have only some colors; look at the result and check if it is a standard IEC-60062 standard, if not try reading the colors in the opposite direction.
A resistor with a single black band has 0Ω resitance.
