Love this


A multimeter can be used to accurately measure the resistance of a resistor but this handy reference guide to the 3 band resistor colour code enables you to quickly work out the value of a resistor.

This A6-sized laminated card has the 3 band colour code on one side and "Keep Calm and Solder On" on the other side. It is printed on gold-coloured paper with a choice of blue, green or red on the front side.

Please choose the background colour you would like for the "Keep Calm and Solder On" message.
