Type MLP 85 C Flatpack, Ultra-Long Life, Aluminum Type MLP 85 C 1/2-Inch Height, 50-Year Life The MLPs high-energy storage and box-shape make it perfect for voltage holdup or ltering in military SEM-E modules, telecom cir- cuit packs and computer cards. The MLP delivers up to 20 joules of energy storage in a 1/2 height with 50 years life at +45 C. You can readily heatsink it to double the ripple-current capability. Ratings up to 250 V can operate at 75% of rated voltage up to 125 C if clamped or potted to prevent expanding beyond 1/2.

The broad, at top and bottom on the MLP are ideal for cooling the capacitor and where cc is the thermal resistance from core to case removing the heat caused by ripple current. and ca from case to ambient. To calculate maximum ripple capability with the MLP attached to a heatsink Ripple Current Capability is set by the maximum use the maximum core temperature and the values for permissible internal core temperature, 88 C. This cc. assures that the case does not inate beyond 0.5 inch height. As an illustration, suppose you operate an insulated MLP332M080EK1C in 65 C air and attach it to a com- Air Cooled. The ripple currents in the ratings tables mercial heatsink with a free-air thermal resistance of are for 85 C case temperatures. For air tempera- tures without a heatsink use the multipliers Ambient 2.7 C/W. Use a good thermal grease between the MLP Temperature, No Heatsink. and the heatsink, and the total thermal resistance is 2.7 +1.7 or 4.4 C/W. The power which would heat the core Heatsink Cooled. Temperature rise from the to 88 C is (88-65)/4.4 or 4.75 W. For an ESR of 31 m, 4.7 W equates to a ripple current of 12.3A.
