Type NHR – SlimpackTM, 3000 hr@150 ºC, Aluminum Electrolytic
Featuring high capacitance at high voltage and temperature, Type NHR-
SlimpackTM offers considerable size and cost advantages over series-parallel banks
of wet tantalum capacitors. Their applications in down-hole tools, military, and
aerospace allow for solutions that use fewer components, lower weight, lower
cost and improved reliability compared with banks of wet tantalum capacitors.
Their rugged construction withstands vibration up to 80g.

Vibration
Mounting: Vibration capability is dependent upon mounting
Level
Vibration Test
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.
