12 / 18 page ![]() POE-D10-00-E-13 SAFETY STANDARDS REGULATED, REINFORCED INSULATION TYPE, AH SERIES Ver: 13 Page: 12 / 18 No Items Performance Testing method Appearance No marked defect. Capacitance Y5P: Within ±10% Y5U: Within ±20% Y5V: Within ±30% SL&CH: Within±2.5﹪or ±0.25pF,Whichever is large. D.F. Y5P,Y5U:5.0% max. Y5V:7.5% max. 7.3.12 Humidity (Under steady State) Set the capacitor for 500±12hours at 40±2 in 90 to 95% ℃ relative humidity. Then capacitor shall be stored for 1 to 2 hours at 1 ※ room condition. Q SL&CH: Less than 30pF=> Q≧ 100+10×C/3 More than 30pF=> Q≧ 200 I.R. Y5P&Y5U&Y5V: 3000M min. SL&CH: 1000M min. 7.3.13 Humidity Loading Dielectric Strength Per Item 7.3.3 Apply the rated voltage for 500±12 hours at 40±2 in ℃ 90 to 95% relative humidity and set it for 1 to 2 hours at 1 ※ room condition. Appearance No marked defect. Capacitance Y5P&Y5U&Y5V: Within ±20% SL&CH: Within±3﹪or ±0.3pF,Whichever is large. I.R. 3000M min. SL&CH: 1000M min. 7.3.14 Life Dielectric Strength Per Item 7.3 3 Impulse Voltage Each individual capacitor shall be subjected to 8kV impulses for three times. After the capacitors are applied to life test. Fig. 2 The specimen capacitors are placed in a circulating air oven for a period of 1000 hours. The air in the oven is maintained at a temperature of 125±3 . Throughout the test, the capacitors are ℃ subjected to an AC425Vrms.(for 0AH type) or AC680Vrms.(for 1AH type) alternating voltage of mains frequency, except that once each hour the voltage is increased to AC1000V(rms.) for 0.1 sec. 7.3.15 Flame Test The capacitor flame discontinues as follows. The capacitor shall be subjected to applied for 15 sec and then removed for 15 sec until 5 cycles. Fig. 5 (unit: mm) Cycle Time 1~4 30sec max. 5 60sec max. |
