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-todate Reliability Report is available by request. RMT Ltd warranties thermoelectric coolers lifetime no less than
250K-300K operating hours under normal application conditions.
Application Tips
1. Never heat up the sub-assembly more than 200˚C.
2. Never use the sub-assembly without an attached
heat sink. Header is NOT a heatsink by itself.
3. Connect TE cooler to DC power supply according
to specified polarity.
4. Do not apply current/voltage higher than specified
max values
Mounting to TEC cold side
Mounting to the
cold side
1. Soldering of object to be cooled.
Method suitable for a TE module with the metallized cold side
(Ordering Options. Item E). Soldering requires careful
procedures:
A. Never overheat TEC (Application Tips. Item 1).
B. Use solder with melting point less than 200ºC.
Header
2. Gluing of object to be cooled.
TEC
Method available by glues with good thermoconductive
properties. Not recommended for high vacuum applications
and long operations at high temperature.

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.
