WebMay 6, 2024 · MOSFETs are sized through dissipation, so 10A means a 0.01 ohm MOSFET dissipates 1W, a 2 milliohm MOSFET dissipates 0.2W, etc, since power = I-squared-R. The amp rating of a MOSFET is not the thing to go for. For a 10A load a 10A MOSFET would be useless, as it would need massive heatsink or water cooling. WebUnplug your printer and detach your bed’s power lines from the mainboard. 2. Connect to your heated bed to the MOSFET’s bed output pins. 3.
