MIL-C-11272E

3.19 Marking. Capacitors shall be marked with the PIN and the manufacturer's name or code symbol. There
shall be no space between the symbols that comprise the PIN. If lack of space requires it, the PIN may appear on
two lines. In this event, the PIN shall be divided between the operating temperature range and capacitance symbols,
as shown in the following example:
CY10C
OR5C
When lack of space prohibits the marking of the PIN on two lines, the PIN may appear on three lines. In this event,
the PIN shall be divided after the two-letter symbol "CY" and between the operating temperature range and
capacitance symbols, as shown in the following example:
CY
10C
OR5C
Marking shall remain legible after all tests.
*
3.19.1 Alternate marking (all styles). Capacitor packaging containers shall be marked with the PIN, capacitance,
capacitance tolerance, voltage, "JAN" brand, and the commercial and Government entity (CAGE) code. Other
markings that in any way interfere with, obscure, or confuse those specified herein are prohibited.
When specified in the ordering data (see 6.2), capacitors shall be legibly marked in accordance with table III.
At the option of the manufacturer, capacitors may be laser marked with the manufacturer's trademark or symbol, the
three-digit capacitor code and tolerance code as follows:
XXX
OR1
F
Where space does not permit, the manufacturer's trademark or symbol may be omitted.
3.20 Workmanship. Capacitors shall be processed in such a manner as to be uniform in quality and shall be free
from pits, corrosion, cracks, chips, and other defects that will affect life or serviceability.
3.20.1 Terminals. Terminals shall be hot-solder-dipped or so coated that soldering can be readily accomplished.
3.20.2 Welding. Surfaces to be welded shall be clean and free from oxides, greases, and other harmful material.
Welds shall be of ample size and good fusing, and shall be free from all harmful defects.
4. VERIFICATION
4.1 Classification of inspections. The inspections specified herein are classified as follows:
a.
Qualification inspection (see 4.4).
Conformance inspection (see 4.5).
b.
4.2 Test equipment and inspection facilities. Test and measuring equipment and inspection facilities of sufficient
accuracy, quality and quantity to permit performance of the required inspection shall be established and maintained
by the supplier. The establishment and maintenance of a calibration system to control the accuracy of the
measuring and test equipment shall be in accordance with ANSI/NCSL Z540-1.
