Standard Options

A range of standard options of RMT TE Modules is available:


Standard TE module types are produced using one of the following ceramics:

  • Alumina Al2O3 100%.
  • Alumina Al2O3 96%.
  • Aluminum Nitride AlN 100%.

The Alumina (100% or 96%) is default for most of standard TE modules (MC, MD, MP, MX series).

The AlN is used for ML Series and optional TEC types manufacturing.

Property Al2O3 100% Al2O3 96% AlN
Thermal conductivity, W/(m×k) 30 24 >170
Thermal expension, 106K-1 7.2 7.0 4.8
Electrical resistivity, Ohm×cm >1014 >1014 >1014

Standard ceramics surface finish:

  • Lapped/Grinded Ceramics Ra<0.6 µm
  • Polished Ceramics Ra<0.1 µm (on request)


All standard TECs are produced in accordance with the requirements of RoHS (Directive 2002/95/EC on restriction of the use of certain hazardous substances in electrical and electronic equipment). RMT standard TECs do not contain restricted substances. They are Lead-Free and are marked correspondingly.

Ordering of «noncompliant» TECs must be specified by customer.
