How do you read inductor color codes?
First two digits indicate the value. Third digit is the power to be applied for the first two , this means it is the multiplier and power of 10. For example, 101 is expressed as 10*101 micro Henry (µH). Suffix or fourth letter or alphabet represents the tolerance value of the inductor.
How do you tell the difference between an inductor and a resistor?
The main key difference between resistor and inductor
- The resistor mainly opposes the flow of current, While Inductor mainly opposes the changes in current flowing through it.
- The resistor cannot store electrical energy, Inductor can store electrical energy in the form of a magnetic field.
What is the color of the 3rd band inductor?
Coming to 3rd band i.e., multiplier is brown in color and its corresponding number is 10. Thus the inductor value is 27 X 10 uH = 270 uH with a tolerance rating of ±5%. In some cases we can have this multiplier band color as gold or silver.
How can you tell the color of an inductor?
The most common are text codes and color codes. Three digit values are in nano Henries (nH) or micro Henries (μH), depending on manufacturers choice Inductors can be marked by colored bands or colored dots. Each color represents a value. note: brown and violet can look very similar on some components.
Where do the dots go on an inductor code?
Surface Mount Device (SMD) or Chip Inductor Codes. 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 are inductors coded according to their size?
Some inductors consist of color dots on surface of the device instead of bands and these are very small in size. Generally these are coded according to the top colored dot on the surface. From this top dot we have to calculate the inductor value in clockwise direction.
