RIPPLE CURRENT
The ripple current listed in the Ratings Table for each
capacitor rating is the maximum permissible rms ripple
current at 40 kHz, 85°C and 2/3 of the 85°C peak voltage.
RIPPLE VOLTAGE
The peak of the applied AC ripple voltage plus the applied DC
voltage must not exceed the DC voltage rating of the cap-
acitor either forward or reverse.
The rms ripple rating at 85°C and 40 kHz is based on a
maximum internal temperature rise of 50°C. The maximum
allowable internal temperature rise decreases linearly
from 50°C to 10°C at an ambient of 125°C.
RIPPLE CURRENT MULTIPLIERS
The rms ripple current capability is shown in the Standard
Ratings Table for each rating at 85°C ambient and at 40 kHz.
For operation at other temperatures and frequencies use
the multipliers shown in the Ripple Current Multipliers Table.
SHELF LIFE
These capacitors have an expected shelf life of ten or
more years when stored at room temperature. Cold
storage has no adverse effects on the capacitor.
Capacitors must be biased such that the negative peak
is not more negative than –3 volts and the positive peak
does not exceed the voltage rating of the capacitor.
The applied DC voltage should be of sufficient magnitude
to prevent polarity reversal in excess of 3 volts at 85°C
and 2 volts at 125°C.
CAUTIONS AGAINST MISAPPLICATION
1. Do not operate at temperatures above the maximum rated.
2. Do not exceed rated WVdc and Surge Voltage of the capacitor.
3. Do not apply ripple voltage or ripple current in excess of
specification limits.
Violations of above can be hazardous and can cause capacitor
failure or equipment failure.
