METALLIZED MYLAR CAPACITORS
ENVIRONMENTAL DATA
APPLICATIONS
Series D Metallized Mylar capacitors are superior
general purpose capacitors for both AC and DC
applications. They are dry-section, non-polar, non-
inductive wound capacitors with high volumetric effi-
ciency and a low cost.
Series D Capacitors come in several styles: Oval
Wrap & Fill; Round Wrap & Fill (DC Style); Axial Epoxy
Case (DE Style); Radial Epoxy Case (D2E Style);
Rectangular Hermetically Sealed (DG Style); Round
Hermetically Sealed (DL Style); Round Wrapped Feed-
Through (DQ Style). They are available in several sizes
including Regular as well as custom sizes to meet
specific customer requirements.
Contact our Engineering Department for special sizes,
configurations, capacitance values and AC applications
with Anti-Corona construction at all frequencies.
Custom metal enclosures are available. Custom
designed Feed Through capacitors (DQ Style) are also
available for filter applications to specific requirements.
OPERATING TEMPERATURE RANGE
Range: -- 55°C to + 125°C, with voltage derating.
LIFE TEST
Series D capacitors shall be capable of withstanding a
test of 1000 hours at + 125°C and 100% of the derated
DC voltage or a test of 250 hours at + 125°C and 140%
of the derated DC voltage. The voltage shall be applied
to each capacitor through its individual current-limiting
resistor as determined from the formula R = 0.025/C,
where C is the nominal capacitance in farads and R is
in ohms.
The test procedures shall be in accordance with MIL-C-
18312, except as noted herein. Not more than one
failure in twelve shall be permitted. Any one of the
following shall be considered a failure.
a. A change in capacitance of more than 10% from
it’s initial value.
b. An increase in Dissipation Factor to a value
greater than 125% of the acceptance limit.
c. A decrease in Insulation Resistance to a value
less than 30% of the acceptance limit for + 25°C.
d. A permanent short or open.

VIBRATION
Series D capacitors shall be capable of withstanding a
vibration test in accordance with MIL-STD-202, Method
201. The following details and exceptions shall apply:
a.
Mounting.
The capacitor body shall be rigidly
mounted by the entire body length to the vibration test
fixture. The leads shall be soldered to rigidly supported
terminals and so spaced that the length of each lead
from the capacitor is 1/2
±
1/8 inch from the edge of
the supporting terminal.
b.
Measurement during Vibration.
During the last
cycle in each direction, an electrical measurement shall
be made to detect intermittent contacts (not to be
confused with "self healing" clearings) or open or short
circuiting.
c.
Examination After Vibration.
Capacitors shall
be visibly examined for evidence of mechanical dam-
age.
MOISTURE RESISTANCE
Series D capacitor Styles DG and DL (Hermetically
Sealed in metal containers) as well as Metal Can
Styles shall be capable of withstanding the moisture
resistance, humidity, and temperature and immersion
cycling or MIL-C-18312. Styles DE and D2E (Epoxy
Case), Styles D and DC (Wrap & Fill) and DQ
(Feed-Through) capacitors are not intended for expo-
sure to high humidity conditions over extended periods
of time.
TERMINAL STRENGTH
Series D capacitors utilize tin-plated, copper-clad steel
wire terminals which shall be capable of withstanding
the following test without mechanical damage to the
capacitor or terminals:
a.
Pull Test.
The capacitor shall withstand a steady
pull of 5 pounds axially to the leads for 1 minute.
b.
Bend Test.
The wire lead terminals shall be bent
at a point of 1/4 inch from the body of the capacitor,
first 90 degrees in one direction, then back to the
original position, and then 90 degrees in the opposite
direction.
