The 'body-end-dot' or 'body-tip-spot' system was used for radial-lead composition resistors sometimes found in vacuum-tube equipment the first band was given by the body color, the second band by the color of the end of the resistor, and the multiplier by a dot or band around the middle of the resistor. They are marked with a single black band. Zero ohm resistors are made as lengths of wire wrapped in a resistor-shaped body which can be substituted for another resistor value in automatic insertion equipment. These values repeat for every decade of magnitude 6.8, 68, 680, and so forth. Resistors use Preferred numbers for their specific values, which are determined by their tolerance. The brown band is a s then a tolerance of ☑%. The value is then 47 x 10 4 Ω, or 470 kΩ. The third band, another yellow, gives the multiplier 10 4. The first two bands represent the digits '4, 7. Any temperature coefficent not assigned its own letter shall be marked "Z", and the coefficient found in other documentation.Ī resistor which (read left to right) displays the colors yellow, violet, yellow, brown.
#Resistor color code table code
The standard color code per EN 60062:2005 is as follows: Color Tight tolerance resistors may have three bands for significant figures rather than two, and/or an additional band indicating temperature coefficient, in units of ppm/ K.Īll coded components will have at least two value bands and a multiplier other bands are optional (italicised below). Resistors manufactured for military use may also include a fifth band which indicates component failure rate ( reliability) refer to MIL-HDBK-199 for further details. Gold signifies that the tolerance is ±5%, so the real resistance could lie anywhere between 4,465 and 4,935 ohms. band D if present, indicates tolerance of value in percent (no color means 20%)įor example, a resistor with bands of yellow, violet, red, and gold will have first digit 4 (yellow in table below), second digit 7 (violet), followed by 2 (red) zeros: 4,700 ohms.band B is the second significant figure.band A is first significant figure of component value (left side).
To distinguish left from right there is a gap between the C and D bands. A 0Ω resistor, marked with a single black band.
