This Product Selection Guide contains information to help select products in the Thermoelectric, Peltier Assemblies category on DigiKey.com
A thermoelectric (TE) module, or Peltier assembly, is a semiconductor-based device that moves heat from one side of the device to the other when low voltage DC power is applied. One face of the module is cooled while the opposite face is heated. This phenomenon is reversed with a change in polarity of the DC voltage. A TE module can generate current when a temperature differential is applied. They are differentiated by heat transfer type, cooling power, current, voltage, and overall dimensions.
SelectionCharacteristics
Heat Transfer Type: Indicates the intended heat transfer media on the two sides of the Peltier assembly.
Power - Cooling: Indicates a device’s rated maximum cooling capacity, under manufacturer-defined test conditions.
Current: This rating indicates the nominal amount of current you would expect the device to draw during normal operation.
Voltage: This rating indicates the nominal amount of voltage you would expect the device to draw during normal operation.
Fan Location: Indicates which sides(s) of the assembly are fan-equipped.
Power - Input: Nominal electrical power input requirement for the Peltier assembly.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
Weight: Indicates the overall weight of the part.
Dimensions - Overall: Indicates the overall length, width, and height of the part.
