Measured by super meg ohmmeter
model SM – 9E (made by TOA).
1-3 or 2-3 (at figure – 1) measured.
To measure after charging with the rated
voltage for 1 minute at room temperature
and normal humidity.

Dielectric
strength
No problem observed.
To charge between 1 ( or 3 ) and 2 (at
figure – 1) with the 2.5 times high of the
rated voltage for 1 to 5 seconds.
6
Current
resistance
No problem observed.
Print rated current for 1 to 5 seconds
between 1-2 (at figure – 1).
7
Solderability
Coverage Min. 90 %
Each termination.
Completely coat parts with flux and
propanol solution and preheat for 1
minute at 120 to 150deg.. Afterwards, dip
parts into solder bath for 2+-0.5 seconds
at 230+-5deg..
Solder level checked by naked eye under
microscope.
