The following MTBF (M

ean Time Between Failure) values were calculated using a combination of manufac-
, if the data was available, and a Bellcore calculation for the remaining parts. The Bellcore
at particular method the components are assumed to be
operating at a 50% stress level in a 40°C ambient environment and the system is assumed to have not been
burned in
nu possible. The manufacturer’s data, when used, is
C, so in that sense the following results are slightly conservative. The MTBF values shown
below are for a 40°C mperatures and other envi-
ronmenta esses (extreme altitude, vibration ater exposure, etc.) cause lower MTBF values.

tion assumes no fan but a passive heat sinking arrangement. Estimated RTC battery life (as opposed to battery failures)
