Information.

every 2,000 hours. There will be no

visual damage and the capacitors will

meet the after-test limits on the following page.

Dissipation Factor

limits are be

low. Measure dissipation factor at 1

MHz when the capacitance is 1 pF to

1,000 pF, and at 1 kHz when the ca

pacitance is greater than 1,000 pF. Dis

sipation factor is equal to DF = 2πfRC,

where f is the test frequency, R is the

equivalent series resistance, and C is

the capacitance. For other capacitance

values, see Figure 1.

Capacitance

100–1000 pF

1100–3300 pF

3600–9100 pF

10,000 pF

Resistance to Solvents:

Subject

the capacitors to three cycles of 3

minute immersion in solvent, 10 strokes

with bristle brush and, where appli

cable,

minute in vapor, per MIL-STD

202, Method 215. Repeat the three

cycles for three solvent mixtures: Iso

propyl alcohol mixture (Solvent 1),

azeotrope mixture (Solvent 3), and

water/propylene-glycol mixture (Sol

vent 4). The marking will not rub off or

smear and there will be no visible dam

age to the capacitor body. Refer to MIL

STD-202 for details.

Failure Rate:

Type CMR capacitors

have specified failure rate levels rang

ing from 0.01% to 1.0% per 1,000

hours. The failure rate level is estab

lished at a 90% confidence level and is

referred to operational life at full-rated

voltage at maximum-rated tempera

ture.

Dissipation Factor

0.00075 max at 1 MHz

0.0014 max at 1 kHz

0.0013 max at 1 kHz

0.0012 max at 1 kHz

Quality Factor (Q)

is the re

ciprocal of dissipation factor.

High-Voltage Stabilization:

subject capacitors with Failure Levels

M, P, and R to a burn-in at twice-rated

voltage, at rated temperature, for a

minimum of 48 hours. Capacitors that

show damage, arcing, breakdown, or

low IR are removed. We reject the lot if

more than 8% of the capacitors fail.

Solderability:

After an 8-hour

steam aging, coat leads with a rosin

flux (R) and immerse in molten

245

°C ±5 °C

60/40 tin/lead solder. Solder

coverage will be no less than 95%

when examined at 10X magnification.

Resistance to Soldering Heat:

Capacitors will meet the requirements

of MIL-STD-202, Method 210 Test Con

dition G. Immerse capacitor leads to

within .250 inches (6.4 mm) of the body

in molten tin/lead solder (260

°C±5 °C)

for 10±2 seconds. Allow to cool. Capaci

tors will meet the after-test limits on

the following page.

Insulation Resistance

for ca

pacitances up to 10,000 pF is greater

than 100 G

at 25

°C,

greater than 10

at 125

°C,

and greater than 5 G

150

°C.

For other capacitance values

and temperatures, see Figure 2.

Marking

of capacitors conforms to

method I of MIL-STD-1285, and in

cludes the type designation, “JAN,”

brand, trademark, source code, date

code, rated voltage, capacitance, ca

pacitance tolerance, and highest rated

temperature. Small capacitors are

marked with the letter “J.”

Withstanding Voltage

is two

times the rated voltage, and can be ap

plied up to 5 seconds without damage.

Life Test:

Subject the capacitors to

maximum operating temperature

(+125

°C

or +150

°C)

with 1.5 times rated

voltage applied for 10,000 hours. Take

readings and make visual observations
