4 band colour code.ġ0 resistors are rarely used today see this page for a list of the more commonly used 5 gold tolerance band resistors. The percent of tolerance in the resistance value may be indicated by a fourth band of color. More online conversion calculators at digi key. Color code calculator will recalculate the color and number of bands in accordance with the chosen value. Up to six color bands are used for resistors. Resistor colour code standard resistor values ohms law resistors in parallel resistors in series. To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change. In this cases the order of magnitude of resistance remain in the same range as was kohm ohm. The color codes chart translates this into 2 00 which equals 2 2 100000 or 2200000 ohms and dont forget the gold 4th band which indicates a 5 tolerance.Ī resistor color code calculator to compute the resistance based on color codes or find the color codes based on a resistance value in ohms kilohms or megaohms.

All resistors above have a silver 10 tolerance band. Resistor 2 has the colors orange orange yellow silver which translates into 3 3 10000 or 330000 ohms and a tolerance of 10. The most common is a four band color code in which the first and second bands represent the first and second significant digit of the resistance value the third band is the decimal multiplier and the fourth band indicates the tolerance. 4-digit SMD resistors from 0.1 ohm to 9.76 M ohms. Basis of the rma resistor color code system the basis of the rma resistor color code system is that all resistance values in ohms may be indicated by means of a system of three colors painted on the resistor in the form of narrow bands dots or as a body color. Resistor color code guide and handy tables that show the ohmic values for commonly used 3-Digit. Click on value in list of examples 5 column on the right and 1 tolerance resistor color code on the left. The resistor color code calculator decodes and identifies a value and tolerance of 5 band wire wound resistors.ġ megohm resistor color code.
