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 storage
temperature range. Thermistor resistance should be properly monitored by the feedback circuit during TEC
operation to avoid the catastrophic damage.
