No te) E ven if the thermo-electric cooler (TEC) is operated within the rated conditions, uncontrolled current loading
or o peration without heatsink may easily damage the module by exceeding the storage temperature range.
Th ermistor resistance sho uld be properly monitored by the feedback circuit during TEC operation to avoid
the catastrophic damage.
