*Preheating for GRM32/43/55
Preheat the capacitor at 120 to 150D for 1 minute.
Immerse the capacitor in an eutectic solder solution at
270W/Y5D for 10W/Y0.5 seconds. Set at room temperature for
24W/Y2 hours (temperature compensating tyoe) or 48W/Y4
hours (high dielectric constant type), then measure.
#Initial measurement for high dielectric constant type
Perform a heat treatment at 150W0/Y10D for one hour and
then set at room temperature for 48W/Y4 hours.
Perform the initial measurement.
Fix the capacitor to the supporting jig in the same manner and
under the same conditions as (10).
Perform the five cycles according to the four heat treatments
shown in the following table.
Set for 24 W/Y 2 hours (temperature compensating type) or
48 W/Y 4 hours (high dielectric constant type) at room
temperature, then measure.
#Initial measurement for high dielectric constant type
Perform a heat treatment at 150W0/Y10D for one hour and
then set at room temperature for 48W/Y4 hours.
Perform the initial measurement.
Apply the rated voltage at 40W/Y2D and 90 to 95% humidity for
500W/Y12 hours. The charge/discharge currentis less than
50mA.
#Initial measurement
Perform a heat treatment at 150W0/Y10D for one hour and
then let sit for 48W/Y4 hours at room temperature. Perform the
initial measurement.
#Measurement after test
Perform a heat treatment at 150W0/Y10D for one hour and
then let sit for 48W/Y4 hours at room temperature, then
measure.
Apply 150% of the rated voltage for 1000W/Y12 hours at the
maximum operating temperature W/Y3D. Let sit for 48W/Y4
hours at room temperature, then measure.
The charge/ discharge current is less than 50mA.
#Initial measurement
Perform a heat treatment at 150W0/Y10D for one hour and
then let sit for 48W/Y4 hours at room temperature. Perform the
initial measurement.
#Measurement after test
Perform a heat treatment at 150W0/Y10D for one hour and
then let sit for 48W/Y4 hours at room temperature, then
measure.
