Resistencia Axial

 

Código de colores

Standard EIA Decade Resistor Values:

• E6 series: (20% tolerance)
• E12 series: (10% tolerance)
• E24 series: (5% tolerance)
• E48 series: (2% tolerance)
• E96 series: (1% tolerance)
• E192 series: (0.5, 0.25, 0.1 and 0.05% tolerance)

Examples

• 3 bands (20% tolerance):

E6 series

Yellow, violet, black --> 47 ohm 20%

Orange, orange, brown --> 330 ohm 20%

Brown, black, red --> 1k 20%

• 4 bands (5% and 10% tolerance):

E12 and E24 series

Green, blue, red, gold --> 5.6kohm 5%

Red, yellow, orange, gold --> 24kohm 5%

Blue, gray, yellow, silver --> 680k 10%

• 5 bands (2%, 1%, 0.5%, 0.25%, 0.1% and  0.05% tolerance):

E48, E96, E192 series

Red, yellow, orange, black, brown --> 243 ohms, 1% precision 5-band resistor

Yellow, violet, gold, gold, yellow --> 4.7 ohms, 5% - this resistor is calculated with the 4-band rule (the yellow band is ignored).

Orange, black, black, brown, brown --> 3.00 k ohms, 1% - note: this is a non-standard 1% (E96) resistor, but some manufacturers make every value from the E24 series with 1% tolerance!

• 6 bands (2%, 1%, 0.5%, 0.25%, 0.1% and  0.05% tolerance):

E48, E96, E192 series

Red, red, brown, brown, brown, red --> 2.21k, 1% 50ppm/°C

White, black, white, brown, red, red --> 9.09k, 2% 50ppm/°C

- do not enter the last band (red in the two examples above)

Ejemplos:

• Thick Film Array Chip Resistor

Resistencia de 0 ohm

Las resistencias de 0 ohms se utilizan como simples puentes en las placas PCB. Estos son usados en sistemas de producción de PCB automatizados, ya que las máquinas no identifican un trozo de alambre como componente electrónico.
