10,000,000 cycles at 25°C and rated voltage. One cycle per second with a time constant of 0.1.

DC leakage current
After application of rated d.c. voltage for 5 minutes at 20°C, the d.c. leakage current shall not exceed (0.006 C_R U_R + 4) µA. Where C_R is the rated capacitance in µF and U_R is the rated d.c. voltage.

Insulation resistance
=> 100MW at 100V d.c., across the insulating sleeve.

Voltage proof
=> 2500V d.c., across the insulating sleeve.

Ripple current
The following values are approximate only, to give an indication of the effects of frequency and temperature on ripple current. More accurate data can be obtained by referring to the Application Notes.

FREQUENCY CORRECTION
Capacitors shall withstand the rated r.m.s. ripple current as given in the table at upper category temperature in circulating air. For frequencies other than those shown in the tables, the following multipliers should be applied to the 100Hz ripple current:

FREQUENCY (Hz)

RATED VOLTAGE D.C.	50	100	500	1k	=> 10k
0 - 25	0.89	1.0	1.05	1.06	1.07
40 - 160	0.81	1.0	1.28	1.33	1.39
200 - 450	0.75	1.0	1.54	1.70	1.89

TEMPERATURE CORRECTION
For ambient temperature other than 85°C the following correction factors should be employed.

AMBIENT TEMPERATURE	FACTOR
30°C	2.5
50°C	2.1
70°C	1.6
85°C	1.0

N.B. The sum of the d.c. and a.c. voltage components should not exceed the d.c. voltage rating.
