Overview: HiTemp ET Series

The HiTemp ET Series of Thermoelectric Modules (TEMs) protect critical electronic devices in emerging applications found in high temperature environments. This typically occurs in outdoor environments where heat generated from surrounding electronics exceeds the temperature of sensitive electronics with maximum operating temperatures of 60~70°C. The HiTemp “ET Series” delivers spot cooling to ensure maximum temperature of device is not exceeded in ambient environments greater than its maximum operating temperature.

Many sensitive devices, such as Lasers and CMOS sensors designed into autonomous systems for vehicles and drones to avoid collision. DLP’s used in 3-D machine vision, advanced lighting and projection may also require cooling in outdoor environments where ambient temperatures exceed its maximum operating temperature condition. The HiTemp “ET Series” product line offers a wide range of heat pumping capacities, geometric form factors and various input voltages.

Laird’s enhanced TEM construction prevents copper diffusion, which commonly occurs for standard grade TEMs in higher temperature environments and prevents degradation in their performance. The HiTemp construction also does not degrade performance like other high temperature modules on the market. The product series maintains a high coefficient of performance (COP) to allow for maximum heat rejection into air environment even with a poor heat sink.

Depending on the application, active cooling may be required to maintain temperatures of sensitive electronics below their maximum operating temperature. The HiTemp ET Series is a preferred cooling method due to its proprietary construction that has shown to not degrade in this environment.

This product line is available in multiple configurations and is ideal for applications that operate in temperatures above 80°C. Assembled with Bismuth Telluride semiconductor material, thermally conductive Aluminum Oxide ceramics, and high-temperature solder construction, the ET Series is designed for higher current and larger heat-pumping applications.

  • High-temperature operation 
  • Reliable solid state 
  • No sound or vibration 
  • Environmentally-friendly 
  • RoHS-compliant
