Thermoelectric Generator Overview
Top Ceramics Al2O3 Ceramics by default (AlN solution is available by request)
Internal Assembly Solder (Lead-Free, Sn-Sb,
Tmelt=230ºC) Pellets (BiTe posts)
Bottom CeramicsTerminal Contacts
(WB pads)
Application Tips1. Never heat TEG module more than 200˚C (TEG is
assembled at 230˚C).2. TEG module to be fixed between hot and cold
exchangers with an optimal thermal contact for thebest efficiency. Improper contact may reduce dTlevel and power output.
3. TEG polarity depends on applied hot and cold sideorientation
Installation1. Mechanical Mounting. TEG is placed between two heat exchangers . This construction is fixed by screws or in
another mechanical way. It is suitable for relatively large TEG modules (with dimensions 15x15mm2 and larger).Miniature TEG types may require another assembling methods.
1. Soldering. This method is suitable for a TEG module with metallized outside surfaces. RMT provides this optionand also makes pre-tinning for TE generators.
2. Glueing. It is an up-to-date method that is used by many customers due to availability of glues with goodthermoconductive properties. A glue is usually based on some epoxy compound filled with somethermoconductive material such as graphite or diamond powders, silver, SiN and others. The application of aspecific type depends on application features and the type of a TEG module.

Terminal Contacts OptionsThe wires by default are of tinned Copper, blank (not insulated). Various options for isolated wires are available by request. The available solutions include isolated wires, isolated color-coded wires, flexible multicore wires and more.
TE Generator terminal contacts can be modified from standard WB pads solution to WB posts type or Flip-Chip if required.
Additional Options
Standard thermoelectric generator height can be modified without performance changes by using ceramics of different thickness. Standard thermoelectric generator height (specified in this datasheet) may be modified in a range -0.5..+1.0mm.
