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%.
