The Capacitor
Vibration – Capacitors shall be tested in accordance with
Method 208 Test Condition D of MIL-STD-202 with the
bodies rigidly clamped. The specimens shall be tested in 3
mutually perpendicular planes for a total of 8 hours with
125% rated DC voltage applied. No evidence of opens,
intermittents or shorts is permitted.
GENERAL ELECTRICAL AND
ENVIRONMENTAL SPECIFICATIONS
Many AVX ceramic capacitors are purchased in accordance
with Military Specifications, MIL-C-39014, MIL-C-11015,
MIL-C-20, MIL-C-55681, and MIL-C-123 or according to
individual customer specification. When ordered to these
specifications, the parts will meet the requirements set forth
in these documents. The General Electrical and
Environmental Specifications listed below detail test
conditions which are common to the foregoing and to most
ceramic capacitor specifications. If additional information is
needed, AVX Application Engineers are ready to assist you.
Shock – Capacitors shall be tested in accordance with
Method 213 Condition 1 (100 Gs) of MIL-STD-202 with the
bodies rigidly clamped. No evidence of opens, intermit-
tents or shorts is permitted.
Thermal Shock and Immersion – Capacitors shall be
tested in accordance with Method 107 Condition A of
MIL-STD-202 with high test temperature (maximum rated
operating temperature) followed by Method 104 of
MIL-STD-202 Test Condition B.
Capacitance – Capacitance shall be tested in accordance
with Method 305 of MIL-STD-202.
Class 1 dielectric to 1000 pF measured at 1 MHz, ± 100
KHz, > 1000 pF measured at 1 KHz ± 100 Hz both at 1.0
± 0.2 VAC.
Class 2 dielectrics (except High K) to 100 pF shall be mea-
sured at 1 MHz ± 100 KHz, > 100 pF measured at 1 KHz ±
100 Hz both at 1.0 ± 0.2 VAC.
Moisture Resistance – Capacitors shall be tested in
accordance with Method 106 of MIL-STD-202 with rated
voltage or 100 VDC whichever is less applied for the first 10
cycles.
Resistance to Solder Heat – Capacitors shall be tested in
accordance with Method 210 of MIL-STD-202 with immer-
sion to .050 of body. AVX Ceralam capacitors are manu-
factured with solder which melts at a temperature greater
than 450°F.
High K dielectrics measured at 1 KHz ± 100 Hz with less
than 0.5 VAC or less applied.
Dissipation Factor – D.F. shall be measured at the same
frequency and voltage as specified for capacitance.
Dielectric Strength – The dielectric strength shall be mea-
sured in accordance with Method 301 of MIL-STD-202 with
a suitable resistor in series with the power supply to limit
the charging current to 50 ma. max.
General Considerations – The application of voltage or
temperature usually causes temporary changes in the
capacitance of Class 2 ceramic capacitors. These changes
are normally in the positive direction and may cause out-of-
tolerance capacitance readings. If a capacitance reading is
made immediately after a dielectric strength or insulation
resistance test and parts are high capacitance, they should
be re-read after a minimum wait of 12 hours.
Insulation Resistance – Insulation Resistance shall be
measured in accordance with Method 302 of MIL-STD-202
with rated voltage or 200 VDC whichever is less applied.
The current shall be limited to 50 ma. max. and the charg-
ing time shall be 2.0 minutes maximum.
Burn-In – (Where specified.) 100% of the parts shall be
subjected to 5 cycles of Thermal Shock per Method 107
Test Condition A of MIL-STD-202 followed by voltage con-
ditioning at twice rated voltage and maximum rated tem-
perature for 100 hours or as specified. After Burn-In, parts
shall meet all initial requirements.
Barometric Pressure – Capacitors shall be tested in
accordance with Method 105 of MIL-STD-202 Test
Condition D (100,000 ft.) with 100% rated voltage applied
for 5 seconds with current limited to 50 ma. No evidence of
flashover or damage is permitted.
Solderability – Capacitors shall be tested in accordance
with Method 208 of MIL-STD-202 with 95% coverage of
new solder.
