1.4
For cylindrical choke coils. Cylindrical choke coils shall be marked with fi ve colored bands. A silver band MIL identifi er of double the
width of the other four bands, located near one end of the coil, identifi es military radio frequency coils; four other bands of equal
width, three indicating the inductance in microhenries and the fourth band indicating the tolerance in percent. Color coding shall
be in accordance with the color code of table. When either the fi rst or second band of the three bands is gold, this band shall rep-
resent the decimal point for inductance values less than 10, and the other two bands shall represent signifi cant fi gures. For induc-
tance values of 10 or more, the fi rst two bands shall represent signifi cant fi gures, and the third band shall represent the multiplier.
For small units, dots may be used instead of bands, when specifi ed. The diameter of the MIL-identifi er dot shall be larger than the
other dots. Typical color coding examples are shown above.
