MTBF reliability prediction
The CE915GM has a predicted MTBF at 35° C and 55° C ambient temperatures, as shown
in
Table 3
. The prediction is based on Telcordia
®
SR-332 Issue 1, Method 1, Case 3 with the
following underlying assumptions:
•
50% default stress ratio for all modeled components
•
Application-specific stress ratios applied for electrolytic capacitors when available
•
Ground Benign in a controlled environment
•
Level II quality grade on all components
•
Mechanical components are not modeled
•
No burn-in or pre-testing specified
•
MTTR specified to be 30 minutes
•
No component-specific thermal rises or other voltage/current stress applied
•
Relex
