Withstanding Voltage
times the rated voltage and can be
applied up to 5 seconds without
damage.
Life Test:
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:
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:
capacitors to printed-circuit boards.
Suspend each board between two
edges separated 3.5 inches with the
capacitor in the center and on the

Moisture Resistance:
the capacitors to 40 2 C at 90 to

25 C, 125 C, and at 25 C—all
perature. The capacitance will meet
the limits of the Characteristic table
in Ordering Information.
Heat Resistance:

hours. Then the insulation resis-
tance will be no less than 5G .
Solderability:
onds in molten solder with 2.5% sil-
ver at 270 5 C, solder coverage will
be no less than 90% when exam-

soldering and no less than 75% for
reflow soldering.
Solder Heat Resistance:
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.
