MTBF
The following MTBF (Mean Time Between Failure) values were calculated using a combination of
manufacturer’s test data, if the data was available, and a Bellcore calculation for the remaining
parts. The Bellcore calculation used is “Method 1 Case 1”. Using this method, 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. Manufacturer’s data has been used wherever possible. The
manufacturer’s data, when used, is specified at 50° C, so in that sense the following results are
slightly conservative. The MTBF values shown below are for a 40° C office or telecommunications
environment. Higher temperatures and other environmental stresses such as extreme altitude,
vibration, and salt-water exposure will lower the MTBF values.

System MTBF (hours) : 123.388 for coolMONSTER/P3 400MHz
Notes:
Fans usually shipped with Kontron Embedded Modules GmbH products have
50,000-hour typical operating life. The above estimates assume no fan, but a
passive heat sinking arrangement.
Estimated RTC battery life (as opposed to battery failures) is not accounted for in
the above figures and needs to be considered separately. Battery life depends on
both temperature and operating conditions. When the Kontron unit has external
power; battery drain occurs from leakage paths.

Environmental Specifications
4.5.1.
Temperature
The Intel
Mobile Pentium
III processor and the Intel
Mobile Celeron
low voltage (LV) CPU
are specified for proper operation when the junction temperature is within the specified range of
0°C to 100°C. The system controller can measure the temperature.
!
Operating: 0 to +70°C (*) (with appropriate airflow)
0 to + 60°C (*) (with appropriate airflow) for 850MHz version
!
Non-operating: -10 to +85
°
C (noncondensing)
Note
:
The maximum operating temperature is the maximum measurable temperature on any
spot on the module’s surface. You must maintain the temperature according to the above
specification.
