3 Specifications

3.4Environmental Specifications

3.4.1Temperature

Operating: (with Kontron Embedded Modules heat-spreader plate assembly):

➤

➤

Ambient temperature: 0°C to 60°C

Maximum heatspreader-plate temperature: 0°C tp 60°C (*)

Non-operating:

➤-30°C to 85°C

See the Thermal Management chapter for additional information.

Note:	*The maximum operating temperature with the heatspreader plate is the maximum measurable temperature
	on any spot on the heatspreader’s surface. You must maintain the temperature according to the above
	specification.

Operating (without Kontron Embedded Modules heat-spreader plate assembly):

➤Maximum operating temperature: 0°C to 60°C (**)

Non operating:

➤-30° to +85°C

See the Thermal Management chapter for additional information.

Note:	**The maximum operating temperature is the maximum measurable temperature on any spot on a module’s
	surface. You must maintain the temperature according to the above specification.

3.4.2Humidity

➤

➤

Operating: 10% to 90% (non condensing)

Non operating: 5% to 95% (non condensing)

3.5MTBF

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”. In that 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. 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 in an office or telecommunications environment. Higher temperatures and other environmental stresses (extreme altitude, vibration, salt water exposure, etc.) lower MTBF values.

➤ System MTBF (hours) : 109418
