   Wattage

   From: bob@bobsville.com   
      
   I need advise on the following:   
      
   The device I am making will use this FET as an output. The device will   
   operate in the range 12 - 24 volts, depending on the users requirement to   
   illuminate a few light bulbs.   
      
   The FET I want to use can handle up to 16 amps at a max of 100v.   
      
   I want to suggest the recommended operating current not exceed 1 amp. as the   
   FET heats up considerably over 1 amp, and due to space restrictions a   
   heatsink is not possible.   
      
   At 24 volts that would be 24 watts, and at 12 volts that would be 12 watts.   
      
   How do I label this device so that a lay person will understand its maximum   
   operating capacity should not exceed 1 amp, depending on their selected   
   operating voltage?   
      
   Most lay users seem to look at wattage and assume that the indicated wattage   
   is for 12 or 24 volt operation.   
      
   Any suggestion appreciated.
