Note) Even if the thermo-electric cooler (TEC) is operated within the rated conditions, uncontrolled current

loading or operation without heatsink may easily damage the module by exceeding the storagetemperature range. Thermistor resistance should be properly monitored by the feedback circuit during TECoperation to avoid the catastrophic damage.
