Type THA,ThinPack, Aluminum Electrolytic Capacitor, 85 ºC
High Energy Density, REACH and RoHS Compliant
At 8.2 mm thin, type THA Thinpack offers the highest energy density
available in a low profile aluminum electrolytic. It’s ideal for the lowest
profile circuits where high capacitance is needed for bulk storage.
Look to type THA to replace arrays of SMT solid tantalum or aluminum
electrolytic capacitors.

Vibration
Mounting: Vibration capability is dependent upon mounting restraint.
All Sizes = 10g
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, 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.

The max ripple current capability is set by the target core temperature of
85 ºC. The Peak to Peak ac must be less than Vr/5.
The ripple currents in the ratings tables are for 65 ºC ambient temperatures.
Temperature rise from the hottest internal spot, the core, to ambient air is
∆T = I
2
(Max ESR)(θcc + θca), recommended max ∆T of 20 ºC
where θcc is the thermal resistance from core to case and θca from case to
ambient. To calculate maximum ripple capability with the THA attached to a
heatsink use the maximum core temperature and the values for θcc.
Example
As an illustration, suppose you operate an noninsulated THA132M060AA0C
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 capacitor
and the heatsink, and the total thermal resistance is 2.7 + 5.42 or 8.12 º
C/W. The power which would heat the core to 85 °C is (85 - 65)/8.12 or 2.46
W. For an ESR of 117 mΩ, 2.46 W equates to a ripple current of 4.58 A.
