at + 25 °C using a capacitance bridge
Dissipation Factor (at 120 Hz)
Limits per Standard Ratings Table. Tested via bridge method, at 25 °C, 120 Hz.
ESR (100 kHz)
Limits per Standard Ratings Table. Tested via bridge method, at 25 °C, 100 kHz.
After application of rated voltage applied to capacitors for 5 minutes using a steady source of power with
1 k
Ω
resistor in series with the capacitor under test, leakage current at 25 °C is not more than described in.
See graph below for the appropriate adjustment factor.
Reverse Voltage
Capacitors are capable of withstanding peak voltages in the reverse direction equal to: 10 % of the DC
5 % of the DC rating at + 85 °C
Vishay does not recommended intentional or repetitive application of reverse voltage
Temperature Derating
