LM4780 Insulator in aussieland

maf_au · 30th July 2005, 11:38 PM

Hi.

Looking for insulators for the LM4780 in Australia.

Berquist agent does not hand out samples here

They do sell the SilPad K10 12' x12" at $80.00 + GST (ouch)

I found a cheaper option at RS Components: RS part 403279 Warth K177-NA-30X30 $41.40 300mmx300mm sheet. Link

Warth's www seems to be down at the moment, but it's at www.warth.co.uk Product is electrical insulator, but thermally conductive.

If anyone has any comments or other alternatives, please pipe up

Oh, and if any Au diy'ers want to share, I'll have some spare material once I decide which to use, happy to share.

Michael

ive had the same problem as you, and up until now, i just simply havent used an lm4780
that sheet of it from rs sound good, wouldn't need to buy any for a long time, and would be whatever shape you wanted

edit,
did you really mean 12 feet by 12 inches on that silpad one? :0

Heh.

I copied that out of the email, I wonder if I can make them stick to it?

They're both 12 inches square, I think...
