What colour codes are used to identify voltage?
120/208/240 Volt AC Wire Colors
- Phase 1 – Black.
- Phase 2 – Red.
- Phase 3 – Blue.
- Neutral – White.
- Ground – Green, Green with Yellow Stripe, or Bare Wire.
What is colour band?
So, colour bands are printed on them to represent the electrical resistance. These colour bands are known as resistor colour code. The resistor colour code was invented in the 1920s by the Radio Manufacturers Association (RMA). All leaded resistors with a power rating up to one watt are marked with colour bands.
What is colour code of resistance?
The colour code used to denote the tolerance rating of a resistor is given as: Brown = 1%, Red = 2%, Gold = 5%, Silver = 10 % If resistor has no fourth tolerance band then the default tolerance would be at 20%.
What is 5S colour?
Typical 5S Color Standards: Yellow. Aisles, Traffic lanes, Walkways, Machine Guards, Work cells. Orange. Inspection or temporary storage locations. Red.
What is color band?
In a color coding technique, the resistors value is marked on the resistors body by using colors. The colors painted on the resistors body are called color bands. All the color bands painted on the resistor body are used to indicate the resistance value and tolerance.
Why do we use dots instead of bands in inductors?
For inductors of a very small physical size, coloured dots may be used instead of bands. In such cases, The silver dot indicating a Military (Mil) specification will be larger than the other dots and will be placed a the beginning of the dot sequence.
How many NH is a 1008ct inductor?

What is the military standard band code for inductors?
The military standard for cylindrical inductors specifies 5 coloured bands The same colours are used as in the EIA 4 band code, but: For band 1, a double width sliver band is used to signify Military Standard. A gold band might be used in either band 2 or band 3.
What is the military standard for cylindrical inductors?
The military standard for cylindrical inductors specifies 5 coloured bands The same colours are used as in the EIA 4 band code, but: For band 1, a double width sliver band is used to signify Military Standard.
