Marking: In accordance with MIL-PRF-49137, except that case sizes A and B, shall be marked as shown in example
1. The front shall be marked with the capacitance value coded in picofarads and the reverse shall be marked with
the dc voltage and the manufacturer's trademark. Case sizes C and D shall be marked as shown in example 2. The
first line will contain the capacitance in picofarads and the capacitance tolerance. The second line will contain the dc
voltage and the manufacturers trademark. Case sizes E, F, and G shall be marked as shown in example 3. The first
line will contain the part number and the second shall contain the date code (year and week), lot code, and
manufacturer's trademark.
At the option of the manufacturer, color coding may be used to mark the capacitance, dc rated voltage, and the
manufacturers trademark on case sizes A and B. The use of two lines, the first line to identify the capacitance, and
tolerance, and the second line, the dc voltage and manufacturers trademark for case sizes C and D. The use of
three lines to mark the date, lot code, and manufacturers trademark on case sizes E, F, and G, as long as it is the
same order as shown in the example.
