Thermal Wizard - Thermoelectric Modules Datasheet


ET4-7-F1-2323-TA-RT-W4.5

Overview: HiTemp Series
The ET4-7-F1-2323-TA-RT-W4.5 high temperature Thermoelectric Module (TEM) uses Laird's enhanced TEM construction preventing performance degrading copper diffusion, which is common in standard grade TEMs operating in high temperature environments exceeding 80 °C. It has a maximum Qc of 18.8 Watts when ΔT = 0 and a maximum ΔT of 69 °C at Qc = 0.
