1.2.1 Capacitance value. The nominal capacitance value, expressed in picofarads (pF) is identified by a three digit number; the first
two digits represent significant figures and the last digit specifies the number of zeros to follow. When the nominal value is less than 10
pF, the letter “R” is used to indicate the decimal point and the succeeding digit(s) of the group represent significant figure(s). 1R0
indicates 1.0 pF; R75 indicates .75 pF; and 0R5 indicates 0.5 pF. See
table IV
for values.
1.2.2 Voltage. The rated voltage for continuous operation at +125°C is identified by a single letter as shown in table I.

3.3.3 Dissipation factor (+25°C). When measured at the frequency and voltage specified in
3.3.2,
the dissipation factor shall be 0.05
percent.
3.3.4 Insulation resistance. At +25°C: minimum of 100,000 megohms or 1,000 megohm-microfarads, whichever is less.
At +125°C: minimum of 1,000 megohms or 10 megohm-microfarads, whichever is less.
3.4 Solderability. In accordance with
MIL-PRF-55681,
except the sample size shall be 5 pieces with zero defectives permitted.
3.5 Moisture resistance. In accordance with
MIL-PRF-55681,
with the following exceptions:
a. Polarizing voltage shall be rated voltage.
b. Testing may be performed on chips with a larger width and/or length as long as they are cut from the same wafer(s) as those used
for production.
3.6 Marking. As a minimum, marking shall be on the package due to the small size of the chips. The package marking shall be in
accordance with
MIL-STD-1285,
except the PIN shall be as specified in paragraph
1.2
with manufacturer’s name or CAGE code and date
code. The manufacturer may, at their option, mark some information on the chips. Suggested marking is the 2 digit EIA capacitance code.
3.7 Manufacturer eligibility. To be eligible for listing as an approved source of supply, a manufacturer shall be listed on the

a sample of
parts agreed upon by the manufacturer and DLA Land and Maritime-VA.
3.8 Certificate of compliance. A certificate of compliance shall be required from manufacturers requesting to be an approved source of
supply.
3.9 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or environmentally preferable materials should
be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and

3.10 Workmanship. In accordance with
MIL-PRF-55681.
4. VERIFICATION
4.1 Qualification inspection. Qualification inspection is not required.
4.2 Conformance inspection.
4.2.1 Inspection of product for delivery. Inspection of product for delivery shall consist of all tests specified in group A of
MIL-PRF-55681.

resonance are not applicable.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see
6.2).
When
packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the responsible
packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Point’s
packaging activities within the Military Service or Defense Agency, or within the military service’s system commands. Packaging data
retrieval is available from the managing Military Department’s or Defense Agency’s automated packaging files, CD-ROM products, or
by contacting the responsible packaging activity.
