Capacitors are placed in a circulating air oven for a period of
1,000 hours. The air in the oven is maintained at a temperature of
125°C ±2°C throughout the test. The capacitors are subjected to
AC 850 Vrms. Each hour the voltage is increased to 1,000 Vrms
for 0.1 seconds. .
1 “Room Condition” is defined as follows: Temperature: 15 ~ 35°C/Humidity: 45 ~ 75%/Atmospheric Pressure: 86 ~ 106 kPa.
