Hi,
We want a LNK30x HV Buck bias supply on a little plug-in PCB which will be plugged in to a socket through which it receiveS its 400Vdc input. It will not be hot plugged or unplugged. Its output back to the main board is 12vdc 160mA.
Do you think this kind of connector system is ok for this voltage?
You need to keep clearance and creepage distances according to applicable standards for the respective PCB material and enviromental conditions. You'll typically leave out contact positions between the HV pins.
Thanks, sorry, this is purely for prototype work, so can we avoid those considerations?
Even if we have just 0.3mm between 400vdc and 12vdc then it will be ok...(wont flash over)...and there'll be solder resist over the traces......mind you , bare soldered pins could be 0.3mm apart......will it flash over?........
I beleive flash-over distance (in air, or along a PCB surface) for 1kV is some 300um?
where did the general preoccupation with TINY become the standard?
just because apple gets away with the smallest ...
and doesn't put connectors on the newer laptops,
doesn't mean you have to
if the traces were 1 mm apart, or G-d forbid, more, how much bigger does your gadget get?
what is the trade off between cost, size, and reliability?
and its a prototype - build it, make it work, then shrink it, if that's what you want
