GUIDE TO APPLICATION
1. AC ripple current: The maximum allowable ripple
current shall be determined from the formula:
Irms =
where
2. AC ripple current: The maximum allowable ripple
voltage shall be determined from the formula :
Vrms =
x Z , where
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:
4. Power dissipation: Power dissipation will be affected
by the heat sinking capability of the mounting surface.
Non-sinusoidal ripple current may produce heating effects
which differ from those shown in the following table. It is
important that the equivalent I
RMS value be established
when calculating permissible operating levels.

5. Cleaning: These capacitors are compatible with all
commonly used solvents, such as TES, TMS, Prelete and
Chloretane. Solvents containing methylene chloride or other
epoxy solvents should be avoided since these will attack the
epoxy encapsulation material.
