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 (DW Style); Round Wrap & Fill (DR Style);

Axial Epoxy Case (DE Style); Radial Epoxy Case (DF

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 (3 Size code) and Miniature (2

Size code) 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:

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.

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.

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 DB and DC shall be capable of withstanding the

moisture resistance, humidity, and temperature and

immersion cycling or MIL-C-18312. Styles DE and DF

(Epoxy Case), Styles DW and DR (Wrap & Fill) and

DQ (Feed-Through) capacitors are not intended for

exposure 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:

Pull Test.

The capacitor shall withstand a steady

pull of 5 pounds axially to the leads for 1 minute.

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.
