FAQ
Standard color code
How to read the color code?
Hold the tolerance band (gold/silver) on the right. First bands are digits, the next is multiplier, the last is tolerance. For 5/6 bands the third is an extra digit.
What is the 6th band?
The 6th band indicates the temperature coefficient in ppm/°C: how resistance varies with temperature. Common in precision resistors.
How do I read the band code?
You hold the tolerance band, the gold or silver one, on the right. The first bands are the digits, the next one is the multiplier and the last one the tolerance: with five or six bands there are three digits.
What does the sixth band mean?
It gives the temperature coefficient in parts per million per degree, that is, how much the value shifts as the resistor warms up. It turns up on precision resistors.
What does the tolerance mean?
It says how far the real value may sit from the nominal one: with a five per cent tolerance a hundred ohm resistor lies somewhere between ninety-five and a hundred and five ohms.
