Application Tips
1. Never heat TE module more than 200˚C (TEC
assembled at 230˚C).
2. Never use TE module without an attached heat sink
at hot (bottom) side.
3. Connect TE module to DC power supply according
to polarity.
4. Do not apply DC current higher than Imax.
Installation
1. Mechanical Mounting. TEC is placed between two heat exchangers . This construction is fixed by screws or in
another mechanical way. It is suitable for large modules (with dimensions 30x30mm and larger). Miniature types
require other assembling methods in most cases.
1. Soldering. This method is suitable for a TE module with metallized outside surfaces. RMT provides this option
and also makes pre-tinning for TE modules.
2. Glueing. It is an up-to-date method that is used by many customers due to availability of glues with good
thermoconductive properties. A glue is usually based on some epoxy compound filled with some
thermoconductive material such as graphite or diamond powders, silver, SiN and others. The application of a
specific type depends on application features and the type of a TE module.

Important notes
1. TEC Performance in this datasheet is specified in typical ambient condition modes (Vacuum, +27ºC; Dry N2,
+50ºC; Dry N2, +75ºC; and Dry N2, +85ºC). The performance may differ under other conditions. Please, use RMT
TECCad software or iTECPad for iPad for detailed analysis, or contact RMT specialists 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 dTmax is specified at zero heatload, while Qmax is specified at zero dT (check Fig.1 for example). TEC
dTmax and Qmax values raise with ambient temperature (check Fig. 2 for example). Please, use RMT TECCad
software or iPad app 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. TEC
cooling performance is less at ambient temperatures below 0ºC. TECs are not suitable to operate 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, required dT level and application heatload. In fact a better performance can be reached at
operating current and voltage lower than Imax and Umax values specified in datasheet.
6. It is strongly recommended to avoid a direct mounting of thermoelectric cooler to pure Copper, Aluminium or
Nickel materials as well as a mounting of objects from these materials on TEC cold side. Any material with high
CTE (Coefficient of Thermal Expansion) may affect on TEC lifetime and even damage TEC in case of improper
mounting, thermal shock and/or temperature cycling. In case of above mentioned materials necessity, it is
recommended to use elastic “soft” solders or glues with large modulus of elasticity (Indium-based solders or
silicon-based thermoconductive glues).
7. RMT Ltd confirms that all RMT thermoelectric coolers are qualified and 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.
