Hi all,
I'm going through the PoElli schematic for next pcb revision. C32 (PoE
input bulk capacitor) caught my eye. It is specified as 47 uF. Datasheet
of LT3748 recommends values ranging from 4.7 uF to 10 uF.
Capacitor sees maximum 57 volts nominal voltage across it. Given 50%
safety margin, voltage rating of capacitor should be at least 85.5 V.
I'd like to replace the capacitor with 10 uF 100 V rated electrolytic, is
that ok?
