15.8 MTBF
The following table contains the mean time between failure (MTBF) in power-on hours (POH). The estimate
is based on the FIT rates of the parts included. FIT rates are based on normalized environmental conditions
of T = 60°C and activation energy (E
a
) of 0.7 eV. Calculations are based on 90% confidence limit.
We estimate that inside the housing, temperature will be 15°C higher than the ambient temperature.
Therefore, the MTBF calculation refers to an ambient temperature of 45°C. The humidity is limited to 60%.
Under these standard conditions, the MTBF for the components of the Draco tera enterprise matrices are
estimated as follows:
