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.
