Note:
(1) These test inspections deviate from screening requirements for class 2 oscillator in MIL-PRF-55310.
(2) The maximum operating and storage temperature of the EX-245 is +85
°
C. The EX-245 shall not be exposed to temperature higher than
+85
°
C at length of time.
(3) The design and construction of the EX-245 can withstand up to 1000g’s constant acceleration
