Page 2 of 8 Thermoelectric Cooling Solutions 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. 46 Warshavskoe shosse.

Do not apply DC current higher than Imax. at hot (bottom) side. 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.
