Vibration
Mounting: Vibration capability is dependent upon mounting restraint. The
optional welded mounting tabs, alone, are not capable of sustaining the high
vibration levels.
To achieve the high vibration levels as published on right, additional mounting
restraint is required.

Available with High Vibration and High Reliability Options
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.
Established Reliability capacitors shall be subjected to a minimum of 100
percent of the dc rated voltage at 85 ºC for 48 hours minimum but not to
exceed 96 hours. During this test, capacitors shall be adequately protected
against temporary voltage surges of 10 percent or more of the test
voltage. After burn-in, the capacitors shall be returned to room ambient
conditions and the dc leakage, capacitance, and ESR shall be measured
with respect to specified limits.

The ripple current capability is set by the maximum permissible internal
core temperature, 125 ºC.
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 MLS attached to
a heatsink use the maximum core temperature and the values for θcc.

Example
As an illustration, suppose you operate an insulated MLS332M060EB1C
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 MLS and
the heatsink, and the total thermal resistance is 2.7 +1.8 or 4.5 ºC/W. The
power which would heat the core to 125 °C is (125 - 65)/4.5 or 13.3 W. For
an ESR of 31 mΩ, 13.3 W equates to a ripple current of 20.7 A, however, the
wire leads are rated for only 20 A.
