I note the cap C71 on the F28069ISo (rev 3) control card appears (from the BOM) to be a 0.1uF 450 Volt Ceramic.
A similar capacitor appears at C17 on the ISO-USB-to-JTAG-II Macro on the HV board.
This seems to me an unsuitable and arguable unsafe type and voltage rating of capacitor to be placed between a 240 volt grid zone and a USB low voltage interface.
Am I missing something - or being unduly conservative? Or is the design "unsafe".
Richard.
