Capacitance is within tolerance
when measured as follows:
1–1000 pF @ 1 MHz
> 1000 pF @ 1 kHz
Dissipation Factor is no more
than 0.1% when measured as
above.
Quality Factor (Q) is as follows
when measured at 1 MHz.

Insulation Resistance is no
less than 100 G
Ω when measured
at 100 Vdc.
Withstanding Voltage is two
times the rated voltage and can be
applied up to 5 seconds without
damage.
Life Test: Subject capacitors to
125
±3°C with 1.5 times rated volt-
age applied for 2000 (+72,–0)
hours. There will be no visual dam-
age and the capacitors will meet
the limits of the table below.
Vibration Resistance: Subject
the capacitors to simple harmonic
motion with an amplitude of 0.06
inches; vary the frequency uni-
formly from 10 to 55 Hz and return
to 10 Hz, all in one minute. Repeat
that cycle continuously for two
hours in each of three mutually
perpendicular directions. There will
be no visual damage and the ca-
pacitors will meet the limits of the
table below.
Bending Test: Solder attach the
capacitors to printed-circuit boards.
Suspend each board between two
edges separated 3.5 inches with the
capacitor in the center and on the
underside. Press in the center of the
suspension until the board flexes
downward 0.1 inches. There will be
no visual damage and the capaci-
tors will meet the limits of the table
below during and after the bend-
ing.
Moisture Resistance: Subject
the capacitors to 40
±2°C at 90 to
95% humidity for 500 (+24,–0)
hours. Return to room ambient for
24 hours. There will be no visual
damage and the capacitors will
meet the limits of the table below.
Temperature Coefficient
and Drift: Measure the capaci-
tors’ capacitance at 25
°C, –55°C,
25
°C, 125°C, and at 25°C—all
±3°C—after stabilizing at each tem-
perature. The capacitance will meet
the limits of the Characteristic table
in Ordering Information.
Heat Resistance: Subject the ca-
pacitors to 125
±2°C for 2 (+1,–0)
hours. Then the insulation resis-
tance will be no less than 5G
Ω.
Solderability: After 2±0.5 sec-
onds in molten solder with 2.5% sil-
ver at 270
±5°C, solder coverage will
be no less than 90% when exam-
ined at 10X magnification for flow
soldering and no less than 75% for
reflow soldering.
Solder Heat Resistance: Sub-
ject the capacitors to molten solder
as above with 5 minutes preheating
at 150
±3°C. There will be no visual
damage and the capacitors will
meet the limits of the table below.
