Heatsink For LM3875 Techdiy Kit

CarlosT · 30th November 2006, 09:40 PM

I was eyeing up this one from Wakefield but I'm concered with the fins interfering with the little caps near the chip of the Techdiy kit.

This is Wakefield 401K or 401-K to make it easier for future searchers

Jack...any feelings on this? The fins protrude .62" from the backplane of the LM3875.

Thanks!

The critical interference would be on the lower left of this picture where the two little caps (C1 and C4) are shown.

Carlos monologue continues...

So yeah...the Wakfield 401-K heatsink sure as sh_t interferes with the little caps...no biggie though because they're small enough that I can prolly bend them almost parallel with the pcb and just about clear the fins. We'll see...stay tuned for next week's episode
