Type CMR
,
High-Reliability, Mica Capacitors
Specifications
Capacitance
is within tolerance when
measured at these frequencies:
1 - 1000 pF @ 1 MHz
> 1000 pF @ 1 Khz
Dissipation Factor
limits are below.
Measure dissipation factor at 1 MHz
when the capacitance is 1 pF to 1000
pF, and at 1 kHz when the capacitance
is greater than 1000 pF. Dissipation
factor is equal to DF = 2pfRC, where f
is the test frequency, R is the equivalent
series resistance, and C is the capaci-
tance. For other capacitance values,
see Figure 1.
Capacitance
Dissipation Factor
100-1000 pF 0.00075 max at 1 MHz
1100-3300 pF 0.0014 max at 1 kHz
3600-9100 pF 0.0013 max at 1 kHz
10,000 pF
0.0012 max at 1 kHz
Quality Factor (Q)
is the reciprocal of
dissipation factor.
Insulation Resistance
for capacitanc-
es up to 10,000 pF is greater than 100
G. at 25 ºC, greater then 10 G. at 125
ºC, and greater than 5 G. at 150 ºC. For
other capacitance values and tempera-
tures, see Figure 2.
Withstanding Voltage
is two times
the rated voltage, and can be applied
up to 5 seconds without damage.
Temperature Coefficient and Capaci-
tance Drift
measure the capacitors’
capacitance at 25 ºC, -55 ºC, 25 ºC, 125 ºC
(or 150 ºC) and at 25 ºC after stabilizing
at each temperature. The capaciance
will meet the limits of the Characteristic
table shown in Ordering Information.
Failure Rate:
Type CMR capacitors have
specified failure rate levels ranging from
0.01% to 1.0% per 1000 hours. The fail-
ure rate level is established at 90% confi-
dence level and is referred to operation-
al life at full rated voltage at maximum
rated temperature.
High Voltage Stabilization:
We sub-
ject 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 dam-
age, arcing, breakdown, or low IR are
removed. We reject the lot if more then
8% of the capacitors fail.
Solderability:
After an 8-hour steam
aging, coat leads with a rosin flux (R)
and immerse in molten 245 ºC ±5 ºC
60/40 tin/lead solder. Solder coverage
will be no less than 95% when examined
at 10X magnification.
Life Test:
Subject the capacitors to
maximum operating temperature (+125
ºC or +150 ºC) with 1.5 times rated volt-
age applied for 10,000 hours. Take
readings and make visual observations
every 2000 hours.
There will be no visual damage and the
capacitors will meet the after-test limits
on the following page.
Resistance to Solvents:
Subject the
capacitors to three cycles of 3 minute
immersion in solvent, 10 strokes with
bristle brush and, where applicable,
½ minute in vapor, per MIL-STD-202,
Method 215. Repeat the three cycles for
three solvent mixtures: Isolpropyl alchol
mixture (Solvent 1), azeotrope mixture
(Solvent 3), and water/propylene-glycol
mixture (Solvent 4). The marking will
not rub off or smear and there will be no
visible damage to the capacitor body.
Refer to MIL-STD-202 for details.
Resistance to Soldering Heat:
Capac-
itors will meet the requirements of MIL-
STD-202, Method 210 Test Condition G.
Immerse capacitor leads to within .250
inches (6.4 mm) of the body in molten
tin/lead solder (260 ºC ±5 ºC) for 10 ±2
seconds. Allow to cool. Capacitors will
meet the after-test limits on the follow-
ing page.
Marking
of capacitors conforms to
method I of MIL-STD-1285, and includes
the type designation, “JAN,” brand,
trademark, source code, date code, rat-
ed voltage, capacitance, capacitance
tolerance, and the highest rated tem-
perature. Small capacitors are marked
with the letter “J”.

High-Reliability, Mica Capacitors
Moisture Resistance:
Capacitors
will meet the requirements of
MIL-STD-202, Method 106F as outlined
here and diagrammed on the
right. Apply 100 V or the rated voltage
(whichever is less) to half of the
capacitors. Don’t apply voltage to
the other half. Refer to MIL-STD-
202 for details.
1. Dry capacitors for 24 hours in a
50±2 °C oven and then allow to
stabilize at room temperature.
2. Subject the capacitors to 20 24-
hour continuous cycles with
relative humidity and temperature
as shown.
3. 4 to 24 hours after completion of
the last cycle the capacitors will
show no visual damage and will
meet the after-test limits below.
