Physical characteristics
Size: 17.6*15.7*2.3mm
Weight: 1.3g±0.2g
Temperature range
Normal operation temperature: -30°C to + 80°C
Extended operation temperature: -40°C to + 85°C*
Storage temperature -45°C to + 90°C
*Note: The performance will be reduced slightly from the 3GPP specifications if the temperature
is outside the normal operating temperature range and still within the extreme operating
temperature range.
