PERFORMANCE CHARACTERISTICS (CONT’D)
1. AC Ripple Current: The maximum allowable ripple
current shall be determined from the formula:
Irms =Pwhere
RESR
P = Power Dissipation in Watts at + 25°C as given below
RESR =The capacitor Equivalent Series Resistance at the
specified frequency.
2. AC Ripple Current: The maximum allowable ripple
voltage shall be determined from the formula:
Vrms =Px Z, where
RESR
Z = The capacitor Impedance at the specified frequency.
The calculations are summarized on the graphs page 7
giving the maximum available ripple voltage as a function
of frequency.
However, the sum of the peak AC voltage plus the DC
voltage shall not exceed the rated DC voltage at + 85°C
of the capacitor. The sum of the negative peak AC voltage
plus the DC voltage shall not allow a voltage reversal
exceeding 15% of the rated DC voltage.
3. AC Ripple Current or Voltage Derating Factor: If these
capacitors are to be operated at temperatures above
+ 25°C, the permissible rms ripple current or voltage shall
be calculated using the derating factors in the table below:
TEMPERATURE DERATING FACTOR
+ 25°C1.0
+ 55°C0.8
+ 85°C0.6
+ 125°C0.4
4. Power Dissipation: Power dissipation will be affected
by the heat sinking capability of the mounting surface.
Non-sinusoidial ripple current may produce heating effects
which differ from those shown in the following table. It is
important that the equivalent Irms value be established
when calculating permissible operating levels.
