CAPACITORS PERFORMANCE CHARACTERISTICS
Notes
• At + 25 °C, the leakage current shall not exceed the value listed in the Standard Ratings Table.
• At + 85 °C, the leakage current shall not exceed 10 times the value listed in the Standard Ratings Table.
• At + 125 °C, the leakage current shall not exceed 12 times the value listed in the Standard Ratings Table
ELECTRICAL PERFORMANCE CHARACTERISTICS
ITEM
PERFORMANCE CHARACTERISTICS
Category Temperature Range
- 55 °C to + 85 °C (to + 125 °C with voltage derating)
Capacitance Tolerance
± 20 %, ± 10 % (at 120 Hz) 2 Vrms 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.
Leakage Current
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
If capacitors are to be used at temperatures above + 25 °C, the permissible rms ripple current or voltage
1.0 at + 25 °C
0.9 at + 85 °C
0.4 at + 125 °C
Maximum Permissible Power
Dissipation at 25 °C
