1.
A-C Ripple Current:
The maximum allowable ripple
current shall be determined from the formula:
where,
P
= Power Dissipation in Watts @ + 25
°
C as
given in the table in Paragraph Number 5
(Power Dissipation).
R
ESR
= The capacitor Equivalent Series Resistance
at the specified frequency.
2.
A-C Ripple Voltage:
The maximum allowable ripple
voltage shall be determined from the formula:
or, from the formula:
V
rms
= I
rms
x Z
where,
P
= Power Dissipation in Watts @ + 25
°
C as
given in the table in Paragraph Number 5
(Power Dissipation).
R
ESR
= The capacitor Equivalent Series Resistance
at the specified frequency.
Z
= The capacitor Impedance at the specified
frequency.
2.1
The sum of the peak AC voltage plus the DC voltage
shall not exceed the DC voltage rating of the capacitor.
2.2
The sum of the negative peak AC voltage plus the
applied DC voltage shall not allow a voltage reversal
exceeding 10% of the DC working voltage at + 25
°
C.
3.
Reverse Voltage:
These capacitors are capable of
withstanding peak voltages in the reverse direction
equal to 10% of the DC rating at + 25
°
C and 5% of the
DC rating at + 85
°
C.
4.
Temperature Derating:
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 as shown:

Recommended Mounting Pad Geometries:
The
nib must have sufficient clearance to avoid electrical
contact with other components. The width dimension
indicated is the same as the maximum width of the
capacitor. This is to minimize lateral movement.

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. It is
important that the equivalent Irmsvalue be
established when calculating permissible operating
levels. (Power dissipation calculated using + 25
