Very Low Profile
The MLP’s high-energy storage and box-shape make it perfect for
voltage holdup or filtering in military SEM-E modules, telecom
circuit packs and computer cards. The MLP delivers up to 20 joules
of energy storage in a 1/2” height with 50 year’s life at +45 ºC. You
can readily heatsink it to double the ripple-current capability. The MLP
is the square-peg component that fits the square-holes in electronic
assemblies.
Highlights
- Low-profile replacement for snap-ins
- Double the ripple capability with a heatsink
- Nearly hermetic welded seal assures 50-year life
- Withstands more than 80,000 feet altitude

Vibration Test
Level
The specimens, while deenergized or operating under the load conditions
specified, shall be subjected to the vibration amplitude, frequency range,
and duration specified for each case size.
Amplitude
The specimens shall be subjected to a simple harmonic motion having an
amplitude of either 0.06-inch double amplitude (maximum total excursion)
or peak level specified above (XXg peak), whichever is less. The tolerance
on vibration amplitude shall be ±10 percent.
Frequency Range
The vibration frequency shall be varied logarithmically between the
approximate limits of 10 to 2,000 Hz.
Sweep Time and Duration
The entire frequency range of 10 to 2,000 Hz and return to 10 Hz shall be
traversed in 20 minutes. This cycle shall be performed 12 times in each
of three mutually perpendicular directions (total of 36 times), so that
the motion shall be applied for a total period of approximately 12 hours.
Interruptions are permitted provided the requirements for rate of change
and test duration are met.

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.
The ripple current capability is set by the maximum permissible internal
core temperature, 88 ºC. This assures that the case does not inflate beyond
0.5 inch height.
The ripple currents in the ratings tables are for 85 ºC case temperatures.
For air temperatures without a heatsink use the multipliers Ambient
Temperature, No Heatsink.
Temperature rise from the internal hottest spot, the core, to ambient air is
∆T = I
2
(ESR)(θcc + θca)
where θcc is the thermal resistance from core to case and θca from case to
ambient. To calculate maximum ripple capability with the MLP attached to a
heatsink use the maximum core temperature and the values for θcc.

Example
As an illustration, suppose you operate an insulated MLP332M080EB1C
in 65 ºC air and attach it to a commercial 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 °C is (88-65)/4.4 or 5.2 W. For an ESR
of 31 mΩ,5.2 W equates to a ripple current of 13 A.
