MFG Part Number: 387004954
Description: ETX9-3-F2-2525-TA-RT-W6
The ET9-3-F2-2525-TA-RT-W6 high temperature thermoelectric cooler uses Laird Thermal Systems' enhanced Thermoelectric Module construction preventing performance degrading diffusion, which is common in standard grade thermoelectric coolers operating in high temperature environments exceeding 80 °C. It has a maximum Qc of 21.4 Watts when ΔT = 0 and a maximum ΔT of 77.9 °C at Qc = 0.
- High-temperature operation
- Reliable solid-state
- No sound or vibration
- Environmentally-friendly
- RoHS-compliant
You can interact with the Performance Curves below to estimate the cooling performance
by entering the thermal and electrical operating conditions for your application.
Click the [Custom Datasheet] button to create a Customized PDF Datasheet.
Please Note: Actual application performance will vary from calculated values based on actual thermal design characteristics.
For maximum performance, be sure to orient the CONTROL side of the TEC against the application to be managed and the AMBIENT side against the heat sink or other heat rejection method. The CONTROL side is always opposite the side with lead attachments. Lead attachment is a passive heat loss and less impactful if located on the side that attaches to the heat exchanger.
Use the sliders, input fields and [UPDATE]
button below to enter your application's electrical and thermal conditions.
Use the Graph Y and X Axis buttons to display a variety of performance curves and use the
Voltage/Current slider to choose the electrical operating point to display performance.
