Description
The «S-Series» is a line of the single stage thermoelectric coolers which are able to provide maximum temperature difference up to 76 (K). These series includes more than 400 standard TECs models. Here you will find TECs with performance characteristics ranges as shown in the table:
| Imax (A) | Umax (V) | Qmax (W) | Height (mm) | Overall dimension (sq.mm) |
|---|---|---|---|---|
| 0.55 - 9.7 | 0.48 - 11.5 | 0.27 - 62 | 1.65 - 4.1 | 1.6 x 3.2 - 21x21 |
- SS – standard rectangular TECs;
- SL – linear TECs;
- SR – round TECs;
- SH – TECs with holes;
- SI – TECs with increased cooling capacity;

Notes and Definitions
Notes and Definitions section should be visited before start surfing catalogue of our products.
| Parameter | Definition |
|---|---|
| Imax, (A) | TEC current at ΔTmax |
| Umax, (V) | TEC voltage at ΔTmax |
| ΔTmax, (K) | Maximum temperature difference between TEC cold and hot side (I=Imax, Qmax=0) |
| Qmax, (W) | Maximum TEC cooling capacity (I=Imax, ΔT=0) |
| Th, (K) | TEC hot side temperature |
| H, (mm) | TEC height |
| Top=AxB, (mm) | Dimensions of the TEC cold side |
| Bottom=CxD, (mm) | Dimensions of the TEC hot side |
|
General Notes: All TEC performance characteristics given for 30°C in vacuum All TEC dimensions given in millimeters To estimate TEC cooling capacity (Q ) at ΔT different from ΔTmax use equation Q=Qmax (1-ΔT/ΔTmax) To estimate TEC temperature difference (ΔT) at Q different from Qmax use equation ΔT = ΔTmax (1- Q/Qmax) |
