Standard Options
A range of standard options of RMT TE Modules is available:
CERAMICS
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)
RoHS COMPLIANCE
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.
