■SPECIFICATIONS AND TEST METHODS
The rated voltage is defined as the maximum voltage which may be
applied continuously to the capacitor.
When AC voltage is superimposed on DC voltage, V
whichever is larger, should be maintained within the rated
voltage range.
Visual inspection.
Using calipers.
No failure shall be observed when 250% of the rated voltage is
applied between the terminations for 1 to 5 seconds, provided the
charge/discharge current is less than 50mA.
The insulation resistance shall be measured with a DC voltage
not exceeding the rated voltage at 25℃ and 75%RH max. and
within 1 minutes of charging.
The capacitance/D.F. shall be measured at 25℃ at the
frequency and voltage shown in the table.
Capacitance
C≦10μF(10V min.)
C≦10μF(6.3V max.)
C＞10μF
The capacitance change shall be measured after 5 min. at
each specified temperature stage.

The ranges of capacitance change compared with the 25℃ value
over the temperature ranges shown in the table shall be within
the specified ranges.
Solder the capacitor to the test jig (glass epoxy board) using a
eutectic solder. Then apply 5N force in parallel with the test
jig for 10±1 sec. The soldering shall be done either with an
iron or using the reflow method and shall be conducted with
care so that the soldering is uniform and free of defects such as
heat shock.
Solder the capacitor to the test jig (glass epoxy board) in the same
manner and under the same conditions as (10). The capacitor shall
be subjected to a simple harmonic motion having a total amplitude
of 1.5mm, the frequency being varied uniformly between the approximate
limits of 10 and 55Hz. The frequency range, from 10 to 55Hz and return
to 10Hz, shall be traversed in approximately 1 minute.
This motion shall be applied for a period of 2 hours in each 3 mutually
perpendicular directions (total of 6 hours).
Immerse the capacitor in a solution of ethanol (JIS-K-8101) and
rosin (JIS-K-5902) (25% rosin in weight proportion). Preheat at
80 to 120℃ for 10 to 30 seconds. After preheating, immerse in
eutectic solder solution for 2±0.5 seconds at 230±5℃,or
Sn-3.0Ag-0.5Cu solder solution for 2±0.5 seconds at 245±5℃.
