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 1200 standard TECs models. Here you will find TECs with performance characteristics ranges as shown in the table.

SL – linear TECs;

Imax (A)
0.55 – 9.7

Umax (V)
0.48 – 11.5

Qmax (W)
0.27 – 62

Height (mm)
1.65 – 4.1

Overall dimension (sq.mm)
1.6 x 3.2 – 21×21

«S-Series» is divided to the next subseries:

SS – standard rectangular TECs;
SL – linear TECs;
SR – round TECs;
SH – TECs with holes;
SI – TECs with increased cooling capacity;
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)
