Thermal and Atmospheric Characteristics

For all Intel
•
relative humidity range: 5% to 90% noncondensing
maximum dew point temperature: 32 °C
•
•
airflow must be at least 300 lfm to keep the LSI53C1020 and LSI53C1030 heat sink
temperature below 80 °C
The following parameters define the storage and transit environment for the Intel
SRCU41L
temperature range: − 40 °C to + 105 °C (dry bulb)
•
•
relative humidity range: 5% to 90% noncondensing
