There is a CTL decision DSH 738 about insulation of body of Y capacitor. If you
are talking about round coated blue Y caps, for Y1 type coated enclosure can be
considered as reinforced insulation except in an area near leg outlet. CTL
considered that coating near leg can break during placement o
I seem to recall that there are some specifications for the insulating coating
in the IEC 60384-14 standard for Y1 caps, but I have not worked with that
standard for a while.
I agree with John Woodgate that a quick fix might be to place a piece of
insulating tape on the surface of the board
I think you have to ask the manufacturer of the capacitors about the
insulation quality of the coating, and also test what happens if the
insulation does break down; the result might be 'safe' but destructive.
At that point, high-voltage spikes on the AC input have to be taken into
account. It
Hello Group,
We are assessing a system that uses class Y1 capacitors for EMC filtering.
Because of space constraints, they are laid down horizontally on the PCB.
This is causing a problem (at least in my mind) where the capacitor body is
now resting on top of the AC input trace. The side of
