D.3: Thermal Considerations 
Cooling Requirements 
When used with XTL-230-18 or XTL 230-36 amplifiers, the XTL-FA-01 operates below maximum 
temperature values, and thus requires no cooling fan. 
When used with XTL-40 amplifiers running continuous currents greater than 12 Adc, 
the XTL-FA-01 should be cooled with an external fan. The fan should have a flow rate of at least 
110 CFM. The filter has been tested using the Comair Rotron MD24B2 24 Vdc powered fan. 
Fan Mounting Guidelines 
Most of the filter’s heat is transferred to ambient air, rather than through the heat plate. Thus, it is 
very important to mount the filter and fan in such a way that the fan can blow up through the filter’s 
cover slots. Mount the filter on edge and mount the fan below it so that it blows up through the 
cover slots. 
There is no heatsink option for the XTL-FA-01 edge filter.
