Hi All,
I am using Netburner's MOD5234 PCB that mounts onto my board which has some transistor logic, optical transceiver and that's about it. My PCB(the one the Netburner mounts to) also has a regulator on it(LM1117) to power the Netburner PCB at 3.3V. The input to the regulator is +5V.
I"m seeing temperatures in the high 90's F on the Netburner and on the optical transceiver. The regulator is a little warm at about the same temperature but that's somewhat expected.(It's a TO-220 package which I goofed and didn't provide a heatsink...DUMMY!) So, I'm confident that with a proper heat sink the regulator should be at a more ambient temperature. I'm still a little confused about the netburner and optical transceiver though.
Does anyone have experience with this netburner PCB and knows if these temperatures are expected? Also, in an electrical system what is the temperature rise from ambient that is the max so you don't degrade the part too quick or do something even worse...like create a fire.
Thanks!!
