Double the Ripple Current: Attach the MLP to an external
heatsink and you can easily double the ripple current
capability and assure long life through cooler operation.
The broad, flat top and bottom on the MLP are ideal for
cooling the capacitor and removing the heat caused by
ripple current.
Ripple Current Capability is set by the maximum permis-
sible internal core temperature, 88 C. This assures that the
case does not inflate beyond 0.5 inch height.
Air Cooled. The ripple currents in the ratings tables are
for 85 C case temperatures. For air temperatures without
a heatsink use the multipliers Ambient Temperature, No
Heatsink.

hottest spot, the core, to ambient air is:

capability with the MLP attached to a heatsink use the
maximum core temperature and the values for cc.
As an illustration, suppose you operate an insulated MLP
in 65 C air and attach it to a commercial heatsink with a
free-air thermal resistance of 2.7 C/W. Use a good thermal
grease between the MLP and the heatsink, and the total
thermal resistance is 2.7 +1.6 or 4.3 C/W. The power
which would heat the core to 88 C is (88-65)/4.3 or 5.35 W.
For an ESR of 100 m , 5.35 W equates to a ripple current
of 6.5A.
