I need a thin heatsink, like the sheet metal heat sink used in SMPS.
But I can't find them on digikey.
Is it called by a different name?
Where can I buy it.
Not that. I saw that on digikey. It's expensive.
The one I am talking about is for a TO-220 package. Its just a plain sheet of aluminum bolted to the chip.
That may not be a catalog item, it's really just bent sheet
metal (or flat stock). Which you could replicate easily enough
with stock from any hardware store, and hand tools, in minutes.
