Products are grouped together by process for MTTF calculations.
(All XpressO output and package types are manufactured with the same process)
Number of Parts Tested:
Number of Failures: 0
Test Temperature:
Number of Hours:
MTTF was calculated using the following formulas:
[1.] Device Hours (devhrs) = (number of devices) x (hours at elevated temperature in °K)
[2.]
[3.] FITS =
Where:
DEVICE-HOURS = 360 x 2000 HOURS = 720,000
ACCELERATION FACTOR =
MTTF =
Failure Rate =
FITS = Failure Rate *1E9 = 64
