are ideal for cooling the capacitor and removing the

heat caused by ripple current.

ripple capability with the MLP attached to a heatsink

use the maximum core temperature and the values for

Өcc.

MLP332M080EK1C in 65 ºC air and attach it to a com-

mercial heatsink with a free-air thermal resistance of 2.7

ºC/W. Use a good thermal grease between the MLP and

the heatsink, and the total thermal resistance is 2.7 +1.7

or 4.4 ºC/W. The power which would heat the core to 88

ºC is (88-65)/4.4 or 4.75 W. For an ESR of 31 m

Ω, 4.7

W equates to a ripple current of 12.3A.
