Thermoelectic Cooling Solutions

Technology Overview

The technology is a thermoelectric cooling component that converts electricity into temperature difference between two surfaces. Such a thermoelectric component is commonly used in laser products to provide effective cooling.

Technology is provided by a manufacturer of high-quality miniature thermoelectric coolers, generators and sensors.

ISO 9001 certified company and the only company certified by  Space Agency to provide thermoelectric coolers for state space projects.  thermoelectric products are used in space equipment working on the distant planets and in outer space. 

A significant share of fibre optics communication channels worldwide is supported by our products. 
Thermoelectric production is Telcordia GR-468 qualified and RoHS compliant.

Technology Features & Specifications

The new TECs provides cooling and temperature stabilization of miniature telecommunication systems. The TECs in the smallest version has planar dimensions less than 1.5 mm2 and height less than 0.55 mm. They are recommended for miniature LD-applications using small headers (TO46 and TO56 and smaller). The new products meet the high-performance requirements of transceiver components with low power consumption.


Standard TEC consists of ceramics plates and BiTe posts (pellets) between them. The dimensions of these pellets inside TEC (as well as the distance between them) are directly connected to TEC performance parameters. Regular TECs have about 100-150 pellets density per 1 cm2. successfully manufactures MD02 Series TECs, in which combination of a miniature cross-section of pellets (0.2х0.2 mm2) and a distance of 100 μm between them allow to assemble 1100 BiTe pellets per 1 cm2 area.

The new TEC provides a next level of miniaturization. The single-stage TECs has a distance of 100 μm between TE pellets has pellets 0.2-0.25-0.3 mm in height and 0.15х0.15 mm2 cross section. This unique combination allows the density of 1600 pellets per 1 cm2.

Potential Applications

The dimensions of pellets, especially their cross section, affect TEC operating current. Smaller cross section means lower operating current. High quantity of internal elements inside a thermoelectric cooler means higher TEC operating voltage. So the benefit of MD015 TECs is in unique low-current/high-voltage combination of operating parameters. It increases the efficiency of power supply units and allows even to skip DC-DC converters in certain applications (for example, telecom transceivers in compact form factor).
