¹ Product performance may be diminished to achieve extended operating temperatures.
Examples include processor throttling, reduced core counts, reduced FPGA functionality
and/or other limitations.
² The test is a non-operational test with operational testing occurring during the last
2 hours of each full cycle (2 cycles total) per MIL-STD-810.
³ Storage temperature is a non-operational test defined per MIL-STD-810, where the product
is brought to the high storage temperature for a minimum of two hours, returned to ambient
temperature and functionally tested. The product is then brought to the low storage temperature
for a minimum of 2 hours and returned to slightly above ambient for functional testing. All tem-
perature transition rates are less than of 10°C/min. One cold/hot cycle constitutes the complete
non-operational storage temperature test.
* For forced convection cooled product, the end user must maintain required volumetric flow rate
(CFM). Contact Mercury for application specific guidance.
** Module conduction cold-plate edge is maintained at or below 71°C.
*** Performance varies with coolant type, fluid temperature and flow rate. Contact Mercury for
application specific guidance.
