w/Amendment 1
4.6.7 Quality factor (Q) (see 3.10). Capacitors shall be tested in accordance with method 306 of MIL-STD-202.
The following detail shall apply:
Test frequency - 1 MHz 200 kHz.
a.
4.6.8 Shock (specified pulse) (see 3.11). Capacitors shall be tested in accordance with method 213 of
MIL-STD-202. The following details and exceptions shall apply:
a.
Mounting: Capacitors shall be rigidly mounted by the body to the test apparatus in such a manner that the
mounting method does not damage the capacitors.
b.
Test-condition letter: I(100G).
c.
Measurements during shock: During shock, an electrical measurement shall be made to determine
intermittent contacts or open- or short-circuiting. The accuracy of the detecting equipment shall be
sufficient to detect any interruption with a duration of 0.5 millisecond or greater.
d.
Examination after shock: Capacitors shall be visually examined for evidence of arcing or mechanical
damage.
4.6.9 Vibration, high frequency (see 3.12). Capacitors shall be tested in accordance with method 204 of MIL-
STD-202. The following details and exceptions shall apply:
a.
Mounting: Capacitors shall be rigidly mounted by the body to the test apparatus in such a manner that the
mounting method does not damage the capacitor.
b.
Test-condition letter: B.
c.
Measurements during vibration: During the last cycle in each direction, and electrical measurement shall
be made to determine intermittent contacts or open- or short-circuiting. The accuracy of the detecting
equipment shall be sufficient to detect any interruption with a duration of 0.5 millisecond or greater.
d.
Examination after test: Capacitors shall be visually examined for evidence of mechanical damage.
4.6.10 Thermal shock and immersion (see 3.13).
4.6.10.1 Thermal shock. Capacitors shall be tested in accordance with method 107 of MIL-STD-202. The
following details and exceptions shall apply:
a.
Test condition letter - B.
b.
Measurements before and after cycling - Not applicable.
4.6.10.2 Immersion. Following temperature cycling, capacitors shall be tested in accordance with method 104 of
MIL-STD-202. The following details and exceptions shall apply:
a.
Test-condition letter - B.
b.
Time after final cycle allowed for measurements - Shall not exceed 30 minutes. Surface moisture shall be
removed by circulating air at room temperature, or wiping with a clean dry cloth, or both.
c.
Examinations and measurements after final cycle - Capacitors shall be visually examined for evidence of
corrosion or mechanical damage; the dielectric withstanding voltage, insulation resistance, capacitance,
and dissipation factor shall then be measured as specified in 4.6.2, 4.6.4, 4.6.5, and 4.6.6, respectively.
