Hence there are fewer values in the 10% tolerance range.ĭownload a pdf version of this page here Learn more about the author read more » If you found this article helpful and you would like to receive product updates and free electronic resources from us then sign up here. They take into account the manufacturing tolerance and are chosen such that there is a minimum overlap between the upper possible value of the first value in the series and the lowest possible value of the next. Two of the most popular are the E12 and E24. 1k 5 color code: Brown Black Red Gold (4 band) 1.2k. 470 Ohm resistor color bands is 'yellow, violet, brown, gold' 510 Ohm.

There are a number of different ranges of values for resistors. 200 Ohm resistor color code is 'red black brown gold' 220 Ohm resistor color code is 'red red brown gold' 300 Ohm - orange black brown gold. Tolerances are important if the accuracy of a resistors value is critical to a designs performance. For example if you were to measure the resistance of a gold tolerance resistor you can guarantee that the value measured will be within 5% of its stated value. Resistors always have a tolerance but what does this mean? It refers to the accuracy to which it has been manufactured. The tolerance band has been ignored.Ĭalculate what the colour bands would be for the following resistor values.
The value of a resistor is given in ohms and is often referred to as its ‘resistance’.Įxample: Band 1 = Red, Band 2 = Violet, Band 3 = Orange, Band 4 = GoldĬalculate the resistor values given by the bands shown below. The bigger the value of a resistor the more it opposes the current flow. A resistor is a device that opposes the flow of electrical current.
