Aluminum oxide insualtion pads for TO-247 - Page 2

Peter Daniel · 2nd May 2003, 03:56 AM

I'm not sure, but I much prefer to work with them. Especially on gainclone chips, I get extra space between pins and heatsink to place feedback resistor there. I believe they are better than mica also and there is no way you accidentally short the device's case to the sink.

just as an offtopic question ..
when mounting the ic's to the heatsinks that are isolated from the chassis (so no ground), do they still need to be isolated? or just some thermal grease?

Peter Daniel · 2nd May 2003, 06:03 AM

If you can make sure that heatsinks won't get in contact with a rest of a chassiss, no insualtors are required, just thermal grease. That's what Cello were doing in their amps.

well the chassis is gonna be out of wood, so i think i'm safe far as that goes

so long as none of the leads touches it anyway .. then i'm in a lot of trouble ..
but that's kind of a given

thanks

I got some more inquiries about those pads. So if there is enough interest, I will order them again. Please e-mail me, if interested.

How much are they each. I could use some for my aleph 2's.

moe29 · 2nd July 2003, 05:05 PM

they'll work for your Aleph 2.

see beginning of thread for price. As long as Peter's not taking
a bath on selling them they'll probably be the same.

Hey Peter, ...I guess we didn't get to good of a response?

after using these babies, nothing else will do!
