Specifications
Marking
Quality Factor (Q) is as follows
when measured at 1 MHz
Insulation Resistance is no less
than 100 GΩ when measured at 100
Vdc
Withstanding voltage is two
times the rated voltage and can be ap-
plied up to 5 seconds without damage.
Life Test: Subject capacitors to
125 ºC ±3 ºC with 1.5 times rated volt-
age applied for 2000 (+72, –0) hours.
There will be no visual damage and the
capacitors will meet the limits of the
table below.
Vibration Resistance: Subject
the capacitors to simple harmonic mo-
tion with an amplitude of 0.06 inches;
vary the frequency uniformly 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 capacitors 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
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.
underside. Press in the center of the sus-
pension until the board flexes downward
0.1 inches. There will be no visual
damage and the capacitors will meet
the limits of thee table below during and
after the bending.
Moisture Resistance: Subject
the capacitors to 40 ±2 ºC 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 thee limits of the
table below.
Temperature Coefficient and
Drift: Measure the capacitors’ capaci-
tance at 25 ºC, –55 ºC, 25 ºC, 125 ºC and
at 25 ºC — all ±3 ºC — after stabilizing
at each temperature. The capacitor will
meet the limits of the Characteristic table
in Ordering Information.
Heat Resistance: Subject the
capacitors to 125 ±2 ºC for 2 (+1,–0)
hours. Then the insulation resistance
will be no less than 5GΩ.
Solderability: After 2 ±0.5 seconds
in molten solder with 2.5% silver at 270
±5 ºC, solder coverage will be no less
than 90% when examined at 10X mag-
nification for flow soldering.
Solder Heat Resistance: Sub-
ject the capacitors to molten solder as
above with 5 minutespreheating at 150
±3 ºC. There will be no visual damage
and the capacitors will meet the limits
of the table below.
