Important notes

1. TEC Performance in this datasheet is specified in two standard ambient condition modes (vacuum, +27ºC and dry

nitrogen (N2), +50ºC). The performance may differ under other conditions. Please, use TECCad software from

RMT Ltd web site or contact RMT or its branch specialists directly for additional TEC performance info.

2. TEC ACR and Umax values are sensitive to ambient temperature. These values can be different from those

specified in the datasheet at other ambient conditions. ACR and Umax raise with ambient temperature increasing.

3. TEC cooling capacity (Qmax) raises with ambient temperature. Please, use TECCad software for additional info or

contact RMT specialists directly.

4. Thermoelectric coolers have the best performance in the temperature range from near room up to +80..90ºC. The

performance is lower at temperatures below 0ºC. TEC is not suitable to work at cryogenic temperatures.

5. Driving a TEC at Imax or Umax doesn’t mean max performance mode. The real optimal mode may depend on

operating conditions and heatload. In fact a better performance can be reached at operating current and voltage

lower than Imax and Umax values specified in the datasheet.

6. It is strongly recommended to avoid a direct mounting of thermoelectric cooler to pure Copper, Aluminum or Nickel

materials as well as a mounting of objects from these materials on TEC cold side. Any material with high CTE may

affect TEC lifetime and/or damage it in case of improper mounting, thermal shock or temperature cycling. In case

of above mentioned materials necessity, it is recommended to use soft solders or glues with large modulus of

elasticity (Indium-based solders or silicon-based thermoconductive glues).

7. RMT Ltd confirms that all thermoelectric coolers meet the requirements of Telcordia GR-468 standard. The up-to-

date Reliability Report is available by request. RMT Ltd warranties thermoelectric coolers lifetime no less than

250K-300K operating hours under normal application conditions.
