A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
The first letter of the color code is matched by order of increasing magnitude. The electronic color codes, in order, are: The electronic color codes, in order, are: 0 = B lack
The international standard IEC 60446 Basic and safety principles for man-machine interface, marking and identification - Identification of equipment terminals, conductor terminations and conductors was a standard published by the International Electrotechnical Commission (IEC) that defined basic safety principles for identifying electrical conductors by colours or numerals, for example in ...
Electrical wiring practices developed in parallel in many countries in the late 19th and early 20th centuries. [7] As a result, national and regional variations developed and remain in effect. (see National Electrical Code, electrical wiring, electrical wiring in the United Kingdom). Some of these are retained for technical reasons, since the ...
25-pair color code – telecommunications wiring; Audio and video interfaces and connectors § Color codes; Optical fibers § Color codes; Electrical wiring – AC power phase, neutral, and grounding wires; Electronic color code AKA resistor or EIA color code (today – IEC 60062:2016) Ethernet twisted-pair wiring – local area networks
A common application of the 25-pair color code is the cabling for the Registered Jack interface RJ21, which uses a female 50-pin miniature ribbon connector, as shown in the following table. The geometry of the pins of the receptacle (right hand image) corresponds to the pin numbers of the table.
Here’s when you may expect to see a drop in your electric bill this fall.
