Insulation resistance: Not less than 10,000 megohms.
Capacitance: Change not more than 0.5 percent of nominal value or 0.5 pF whichever is greater, from
initial 125°C value.
Dissipation factor: Not to exceed 0.007.
Performance check: Capacitors shall meet the following requirements:
For performance check:
Insulation resistance: 100,000 megohms minimum.
Capacitance: Change not more than 0.5 percent of nominal value or 0.5 pF whichever is greater, from
initial 125°C value.
Dissipation factor: Not to exceed 0.0025.
Temperature coefficient and capacitance drift: The temperature coefficient and capacitance drift shall be within
the limits specified in table II.

Qualification: With respect to products requiring qualification, awards will be made only for products which are, at
the time of award of contract, qualified for inclusion in the applicable Qualified Products List whether or not such
products have actually been so listed by that date. The attention of the contractors is called to these
requirements, and manufacturers are urged to arrange to have the products that they propose to offer to the
Federal Government tested for qualification in order that they may be eligible to be awarded contracts or orders
for the products covered by this specification. Information pertaining to qualification of products may be obtained
from Defense Supply Center Columbus, P. O. Box 3990, Columbus OH 43216-5000.
