Test Method
Solder the capacitor and gum
up the body to the test jig
(glass epoxy board) by resin
Resin (Adhesive)
(adhesive).
The capacitor should be firmly soldered to the supporting lead
wire, 1.5mm in total amplitude, with about a 20 minutes rate of
vibration change from 10Hz to 2000Hz and back to 10Hz.
This motion should be applied 12 times in each of 3 mutually
perpendicular directions (total of 36 times).
The acceleration is 5g max.
Solder the capacitor and gum
up the body to the test
jig (glass epoxy board) by
Resin (Adhesive)
resin (adhesive).
Three shocks in each direction should be applied along 3
mutually perpendicular axes to and from of the test specimen
(18 shocks).
The specified test pulse should be half-sine and should have a
duration: 0.5ms, peak value: 100g and velocity change: 4.7m/s.

Set the capacitor for 1000±12 hrs. at 85±3°C in 80 to 85%
relative humidity.
Pre-treatment:
Capacitor should be stored at 125±3°C for 1hr., then placed
at room condition* for 24±2 hrs. before initial measurements.
Post-treatment:
Capacitor should be stored for 1 to 2 hrs. at room condition.*
Apply the rated voltage for 1000±12 hrs. at 85±3°C in 80 to
85% relative humidity.
Pre-treatment:
Capacitor should be stored at 125±3°C for 1hr., then placed
at room condition* for 24±2 hrs. before initial measurements.
Post-treatment:
Capacitor should be stored for 1 to 2 hrs. at room condition.*
Impulse Voltage
Each individual capacitor should be subjected to a 5kV
impulses for three times. Then the capacitors are applied to life
test.

Applied Voltage
AC510V(r.m.s.), except that once each hour the voltage
is increased to AC1000V(r.m.s.) for 0.1 sec.
Pre-treatment:
Capacitor should be stored at 125±3°C for 1hr., then placed
at room condition* for 24±2 hrs. before initial measurements.
Post-treatment:
Capacitor should be stored for 1 to 2 hrs. at room condition.*
* "Room condition" Temperature: 15 to 35°C, Relative humidity: 45 to 75%, Atmospheric pressure: 86 to 106kPa
