I'm building a 3D printer from scratch (My first one, so yeah, tall order), so I'm buying all the parts separately, now one of the things I bought was a 300x300 12v 25A Silicon heaterbed (Yeah, I know, should have gone for a higher voltage, but that's the only one I could get at the time)
I have a RAMPS 1.4 board in all it's crappy MOSFET glory, so I tried giving my math skills a shot in trying to find a decent MOSFET that won't explode, though I'm still having issues deciding. And due to where I live, getting anything very specific is not the easiest thing to do.
So can anyone recommend a MOSFET that I can use to switch 25A and mention if it will need a heatsink?
I live in South Africa, So one place that I can get them from is from RABTRON Electronincs
There are a couple other places, but I'd prefer to get them here if I can.
