The OTX20-12-F0-0406-22-W2.25 is a high-performance, miniature thermoelectric cooler. The OTX20-12-F0-0406-22-W2.25 is primarily used in applications to stabilize the temperature of sensitive optical components in the telecom and photonics industries. It has a maximum Qc of 1.7 Watts when ΔT = 0 and a maximum ΔT of 72.9 °C at Qc = 0.
- Miniature footprint
- Precise temperature control
- Reliable solid-state operation
- No sound or vibration
You can interact with the Performance Curves below to estimate the cooling performance by entering the thermal and electrical operating conditions for your application.

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 HEATSINK 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.
