Questions
How big is the Main MOSFET Cooler PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Main MOSFET Cooler use?
20 parts, built around the NXFT15XH103FA2B050. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Main MOSFET Cooler KiCad files?
From the EosinY/ElectronicLoad-Cooler repository on GitHub, at the commit this page was made from: the board is Main_MOSFET_Cooler.kicad_pcb and its schematic Main_MOSFET_Cooler.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main MOSFET Cooler design in my own project?
Its repository states no licence, so its author keeps all rights: ask EosinY before reusing the design.
