MIL-PRF-87217A
3.8 High-impedance temperature and voltage ramp. When tested as specified in 4.7.4, capacitors shall withstand
the extremes of high and low temperatures without visible damage. Any dc leakage current greater than 0.05 A
during ramp test shall be considered a failure.
3.9 Insulation resistance. When measured as specified in 4.7.5, the insulation resistance shall be not less than
the values specified (see 3.1).
3.10 Capacitance. When measured as specified in 4.7.6, the capacitance shall be within the applicable tolerance
specified (see 3.1).
3.11 Dissipation factor. When measured as specified in 4.7.7, the dissipation factor shall not exceed 0.15
percent.
3.12 Seal. When capacitors are tested as specified in 4.7.8, there shall be no repetitive bubbling, and for
liquid-impregnated capacitors, there shall be no evidence of leakage.
3.13 Radiographic inspection. When the capacitors are radiographed in accordance with 4.7.9, there shall be no
evidence of improperly made connections, substandard soldering, structural weakness, or attached solder particles
or slivers (see appendix).
3.14 High impedance dc life. When tested as specified in 4.7.10, capacitors shall meet the following
requirements:
a. Insulation resistance (terminal to terminal): Shall meet the initial requirements (see 3.1).
b. Capacitance: Shall meet the initial requirements (see 3.1).
c. Dissipation factor: Shall meet the initial requirements (see 3.1).
d. Visual inspection: There shall be no corrosion, leakage of impregnant, or mechanical damage either during
or after the test.
3.15 Solderability. When capacitors are tested as specified in 4.7.11, the dipped portion of the terminals shall
conform to the solid-wire termination criteria of method 208 of MIL-STD-202.
3.16 Marking. Marking of capacitors shall conform to method I of MIL-STD-1285, and shall include the part
number, "JAN" marking, date code, lot symbol, manufacturer's source code, capacitance (in F), capacitance
tolerance, and rated voltage.
Example of marking:
M87217/01-
-
PIN (may be on one line if space permits).
2107A
.018 F 5% 50 V
-
Capacitance, capacitance tolerance, and rated voltage.
JAN 8433A 12345
-
"JAN" marking, date code, lot symbol and source code.
AAA
-
Serialized marking, each part, alpha or numeric (no limit on the
number of spaces).
The manufacturer shall provide for lot traceability by date code and lot symbol. Manufacturing records shall include
these same date codes and lot symbols.
3.16.1 JAN and J marking. The United States Government has adopted, and is exercising legitimate control over
the certification marks "JAN" and "J", respectively, to indicate that items so marked or identified are manufactured to,
and meet all the requirements of specifications. Accordingly, items acquired to and meeting all of the criteria
specified herein and in applicable specification, shall bear the certification mark "JAN" except that items too small to
bear the certification mark "JAN" shall bear the letter "J". Items furnished under contracts or orders which either
permit or require deviation from the conditions or requirements specified herein and in applicable specifications shall
not bear "JAN" or "J". In the event an item fails to meet the requirements of this specification and the applicable
specification sheets or associated specifications, the manufacturer shall remove completely the military part number
