A wide silver band located at one end of the coil identifies military radio fequency coils. Therefore the value of inductor can be determined by reading the colors of inductor body and comparing them with color code chart.

Color coding is in accordance.

How to read inductor colour code. The table below shows the significance of each color. In some cases only a single coloured dot is. The color codes for inductors are identical to that of a resistor so if you are familiar with resistors this should be very easy.

The dots do not indicate polarity. It is to be noted that the result of this color coded value is in the unit of micro henry uh. Dot 3 indicates the number of zeroes to be added.

This will be a simple guide to reading inductor color codes. Each color represents a value. The tricky part is remembering the results from this will be in microhenrys not just henrys.

The next three bands indicate the inductance in micro henries and the fourth band is the tolerance. First break down the bands. Dots 1 and 2 indicate the inductance in nanohenries.

To convert from colours to value. Hover the mouse over the coloured bands on the image of the inductor to display the colour selector box then click on the required colour. 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.

For inductors of a very small physical size coloured dots may be used instead of bands. Decibel dbw electronic filter. Values below 10 nh.

Molded coated inductor color coding cylindrical molded choke coils are marked with five colored bands. This design makes it very easy for you to integrate the system into your own project. Sometimes the precision of the inductor will be marked using a final letter f g j k or m f 1 g 2 j 5 k 10 m 20 color code markings edit.

Surface mount device smd or chip inductor codes. Repeat for all bands tolerance is optional. We have an inductor with the code 332f.

Other parts are marked with three color dots. The table below shown gives the color corresponding to the numerical values for a four band inductor. The colour bands will be displayed below on the image of the inductor.

The system consists of individual components including a controller a stepping motor a foot switch power adapter and output shaft. Inductors can be marked by colored bands or colored dots. Gray red black 82 nh brown red brown 120 nh yellow violet red 4700 nh.

The inductance is 3310 2 mh 33mh. The tolerance for f 1.
