The Center-Hole TEM series is suitable for various cooling and heating applications which generally require medium pumping capacity. Typical application areas include industrial and electrical equipment as well as laboratory and opto-electronics. Standard substrates are lapped with ± 0.025 mm tolerance. These TEMs are also available with different configurations.

- round type with center hole
The peltier coolers in our Round Center-hole Thermoelectric Module series are suitable for cooling and heating applications that generally require intermediate pumping capacity. The round shape makes these thermoelectric coolers an ideal solution for special form-factor requirements. Typical applications for these TECs include industrial equipment, electrical equipment, laboratory instrumentation and opto-electronics. Standard substrates are lapped with +/-0.025mm tolerance.

- multi-hole modules
The Multi-Hole TEM series has been specifically designed for ø 5.6 mm CAN type laser diodes. The increased contact area between the TEM and laser diode package enables more uniform cooling with the target temperature being achieved more rapidly. The optimized thermal contact area results in very stable thermal performance for laser diodes. The standard series is available for laser diodes with diameters ranging from 3.5-9.0 mm. For other specific laser diode sizes or design requirements please contact us.

Type 2 (T2) TEMs feature a "porch" for more accurate heat distribution.
This makes the L2 dimensions slightly longer than the L1 dimension.
| Imax: | Maximum input current in amperes at Qc=0 and ΔTmax |
| Vmax: | Maximum DC input voltage in volts at Qc=0 and ΔTmax |
| ΔTmax: | Maximum temperature differential in °C at Qc=0 and Imax |
| Qcmax: | Maximum heat pumping capacity in watts at Imax and ΔT=0 |
| T hot: | Temperature of TEM hot side during operation |
