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 between 5 sec-
onds and without damage: with 50 mA
or less current.
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: Mechanical flexure
of 2 mm bending length without crack-
ing or visual damage. Capacitance
change not to exceed ±1% or 1 pF
whichever is greater.
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
at 5 Vrms or less.
Press in the center of the suspension
until the board flexes downward 0.1
inches. There will be no visual damage
and the capacitors will meet the limits
of the 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 the 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 ca-
pacitors 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 Sn-PB between
molten and solder at 235 ±5 ºC, solder
coverage will be no less than 75% when
examined at 10X magnification for flow
soldering.
Solder Heat Resistance: Sub-
ject the capacitors to molten solder at
250±5 ºC for 5±0.5 seconds after 10 to
30 seconds pre-heating at 80 to 120 ºC.
There will be no visual damage and the
capacitors will meet the limits of the
table below.
