Thermoelectric sub-assemblies
“Butterfly” 14pin Sub-Assemblies
-
-
“Butterfly” packages is the standard format for optical Telecom transmissions and laser diode pumps. The most common type is 14pin package with CuW of CuMo base plate for better thermal conductivity. The open space inside allows to install a thermoelectric cooler with dimensions up to 10x16mm. RMT Ltd provide a range of sub-assemblies - thermoelectric cooler installed in “Butterfly” package - with cooling capacity up to 25W (at standard room conditions). The sub-assemblies are based on RMT thermoelectric cooler Series: ML06, ML07, MDL06 and MD10. Wide range of manufacturing options is available - ceramics material and surface conditions, pinout configurations, thermistors and other optimizations for final application.

Note: There are several thermoelectric coolers series optimized for mounting in “Butterfly” 14pin package: ML06, ML07, MDL06 and MD10. The difference between series is in combination of performance parameters. ML06 Series contains common telecom industry thermoelectric coolers. Sub-assemblies with ML07 Series TECs have the increased cooling capacity. MDL06 Series thermoelectric coolers have up to 100% higher Qmax value and recommended for applications with high heatload. Solutions with MD10 TECs have special combination of Imax/Umax parameters. ML06, ML07 and MDL06 Series thermoelectric coolers are available on different ceramics - Al2O3 and AlN. Please, select the series and(or) ceramics type to get the list of standard sub-assembly solutions and datasheets.

Important Note: thermoelectric coolers can be manufactured on standard 0.5mm and thin 0.25mm ceramics. This adds an additional flexibility to performance and height optimization in a particular application. It is also possible to combine various ceramics thicknesses to achieve the most optimal results for TEC height, performance and power consumption. Mind, please, that with different ceramics thickness TECs may have different performance having the same geometry. Here is the example (please, click to zoom in):
Please, use On-Line Assistant to find the most optimal thermoelectric cooler by dimensions and performance parameters. The detailed analysis of TEC performance and power consumption can be made with free TECCad software for Windows or special iTECPad app for iPad (available free on App Store).
