Datasheet

7-6. Electrical endurance: (Testing method : IEC 60384-2)
125% of rated voltage shall be applied to the capacitor at a temperature of +85±2 °C for 2000 hours. (87.5% of rated voltage shall
be applied to the capacitor at a temperature of +105±2 °C for 2000 hours) And then the capacitor shall be subjected to standard
atmospheric conditions for 1 to 2 hours ,after which measurement shall be made.
The load resistor in series with the capacitor shall be 20Ω to 1KΩ. For other procedures, refer JIS C5102-1994.
Performance:
Capacitance change: Δ C/C : ≤ ± 5%
DF change: Δtan δ : ≤ 1.0% at 1 KHZ
Insulation resistance: ≥ 50% of limit value
7-7. Δ T :
Less than +8°C
Method of measuring inherent temperature rise
Inherent temperature of capacitor shall be
measured by keeping away from heat influence of surrounding components after
attaching thermocouple to the capacitor as show below. (They shall be measured in normal temperature.)
Measurement shall be down by soldering capacitor on the opposite side of the printed circuit board etc. in case of being influenced
by heat of surrounding components.
Besides, they shall be
measured in calm condi
tion by putting capacitor into box etc. in case of being influence by convection or wind.
