I=0.02CV or 5mA, whichever is smaller.

Where, I : Max. leakage current (µA), C : Nominal capacitance (µF), V : Rated voltage (V)  (at 20℃ after 5 minutes)

Dissipation Factor
(tanδ)

 

0.25 max.(at 20℃, 120Hz)

Low Temperature
Characteristics

Capacitance change  C(-25℃)/C(+20℃)≧0.7(at 120Hz)

Insulation Resistance

When measured between the terminals that are connected to each other and to the mounting clamp on the insulating sleeve covering the case by using an insulation resistance meter of 500Vdc, the insulation resistance shall not be less than 100MΩ.

Insulation
Withstanding Voltage

When a voltage of 2,000Vac is applied for 1 minute between the terminals that are connected to each other and to the mounting clamp on the insulating sleeve covering the case, there shall not be electrical damage.

Endurance

The following specifications shall be satisfied when the capacitors are restored to 20℃ after subjected to DC voltage with the rated

ripple current is applied (the peak voltage shall not exceed the rated voltage) for 5,000 hours at 85℃.

Capacitance change

≦±20% of the initial value

 

D.F. (tanδ)

≦200% of the initial specified value

Leakage current

≦The initial specified value

Shelf Life

The following specifications shall be satisfied when the capacitors are restored to 20℃ after exposing them for 500 hours at 85℃ without

voltage applied. Before the measurement, the capacitor shall be preconditioned by applying voltage according to Item 4.1 of JIS C 5101-4.

Capacitance change

≦±20% of the initial value

 

D.F. (tanδ)

≦200% of the initial specified value

Note : The endurance of capacitors is reduced with internal heating produced by ripple current at the rate of halving the lifetime with every 5 to 10℃ rise. When long life performance is required in actual use, the rms ripple current has to be reduced. Also, for the RHA series capacitors, using them at operating voltage less than their rated voltage can extend their lifetime. For details, please contact a representative of Nippon Chemi-Con.
