Bad boys rape our young girls but Violet gives willingly. MnemonicsĪ useful mnemonic matches the first letter of the color code, by order of increasing magnitude. Polyester film and "gum drop" tantalum electrolytic capacitors are also color coded to give the value, working voltage and tolerance. A broad black band was applied to some tubular paper capacitors to indicate the end that had the outer electrode this allowed this end to be connected to chassis ground to provide some shielding against hum and noise pickup. Įxtra bands on ceramic capacitors will identify the voltage rating class and temperature coefficient characteristics. The other end of the resistor was colored gold or silver to give the tolerance, otherwise it was 20%. 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.

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. #270 ohm resistor color code how to
The Resistor Colour Code system is all well and good but we need to understand how to apply it in order to get the correct value of the resistor.A 0Ω resistor, marked with a single black band. The Standard Resistor Colour Code Chart : Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. High-power resistors that can dissipate many watts of electrical power as heat, may be used as part of motor controls, in power distribution systems, or as test loads for generators. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
