3.7. Environmental Specification
3.7.1. Temperature Specification
Kontron defines following temperature grades for Computer-on-Modules in general. Please see chapter 'Product
Specification' for available temperature grades for the COMe-cBT6
Temperature Specification Operating Non-operating Validated Input Voltage
Commercial grade 0°C to +60°C -30°C to +85°C VCC: 4.75 - 20V
Extended Temperature (E1) -25°C to +75°C -30°C to +85°C VCC: 12V
Industrial grade by Screening (XT)
-40°C to +85°C -40°C to +85°C VCC: 12V
Industrial grade by Design (E2)
-40°C to +85°C -40°C to +85°C VCC: 4.75 - 20V
Operating with Kontron heatspreader plate assembly
The operating temperature defines two requirements:
» the maximum ambient temperature with ambient being the air surrounding the module.
» the maximum measurable temperature on any spot on the heatspreader's surface
Test specification:
Temperature Grade Validation requirements
Commercial grade at 60°C HSP temperature the CPU @ 100% load needs to run at nominal frequency
Extended Temperature (E1) at 75°C HSP temperature the CPU @ 75% load is allowed to start speedstepping for thermal protection
Industrial grade by Screening (XT)
at 85°C HSP temperature the CPU @ 50% load is allowed to start throttling for thermal protection
Industrial grade by Design (E2) at 85°C HSP temperature the CPU @ 50% load is allowed to start throttling for thermal protection
Operating without Kontron heatspreader plate assembly
The operating temperature is the maximum measurable temperature on any spot on the module's surface.
3.7.2. Humidity
» 93% relative Humidity at 40°C, non-condensing (according to IEC 60068-2-78)
