Test conditions
(based on JIS C 5101−1 and JIS C 5101−3)
After applying the rated voltage for 1000⁺³⁶ h
without discontinuation via the serial resistance
of 3Ω or less at a temperature of 85 ^+−2 C, leave
the sample at room temperature / humidity for
1 to 2h and measure the value.
A force is applied to the terminal until it bends
to 1mm and by a perscribed tool maintain the
condition for5s.(See the figure below)

Dimensions
Refer to "External dimensions"
Measure using a caliper of JISB 7507 Class 2
or higher grade.
Resistance to solvents
Solderability
The indication should be clear
3/4 or more surface area of the solder coated
terminal dipped in the soldering bath should
be covered with the new solder.
Vibration
Capacitance Measure value shoule not fluctuate during the
measurement.
