In
EC TYPE
series color band are marked for identification. These bands indicate
inductance value and tolerance. For values below 0.1uH, Gold indicates the decimal point
and the next three bands indicate inductance value. There is no tolerance marked for values
below
0.1uH.
In
EC22
series due to limitation in size, only three color bands indicating inductance value
is marked without decimal value and tolerance.
