No te. Even if the thermo-electric cooler (TEC) is operated within the rate d conditions, uncontrolled current loading
or operation without heatsink may easily damage the mod ule by exceeding the storage temperature range.
Th ermistor resistan ce should be properly mon itored by the feedback circuit during TE C operation to avoid
the catastrophic damage.
