4.3 Reliability Specifications
4.3.1 Mean Time Between Failure (MTBF) Specifications
Calculation Type: MTBF/FIT Rate
Standard: Telcordia* Standard SR-332 Issue 1
Methods: Method I, Case I, Quality Level II
The calculation results were generated using the references and assumptions listed.
This report and its associated calculations supersede all other released MTBF and
Failure in Time (FIT) calculations of earlier report dates. The reported failure rates do
not represent catastrophic failure. Catastrophic failure rates will vary based on
application environment and features critical to the intended function.
4.3.1.1 Environmental Assumptions
• Failure rates are based on a 40° C ambient temperature.
• Applied component stress levels are 50 percent (voltage, current, and/or power).
• Ground, fixed, controlled environment with an environmental adjustment factor
equal to 1.0.
4.3.1.2 General Assumptions
• Component failure rates are constant.
• Board-to-system interconnects included within estimates.
• Non-electrical components (screws, mechanical latches, labels, covers, etc.) are
not included within estimations.
• Printed circuit board is considered to have a 0 FIT rate.
