Adapt PCB from Eagle to KiCAD and increase perfomance Adapt PCB from Eagle to KiCAD and increase performance from current 80A to 200A with peaks of 400A (specify heatsink for the design). Theoretically, used MOSFETs (FDMT80080DC, two in parallel) should be capable to handle 200A requested currents if they are cooled properly, but heatsink must be calculated. Also the Würth press-fit elements are already capable to handle 200A in theory. Probabl... 9 エレクトロニクス, 電気工学, PCBレイアウト, 回路設計 Jun 17, 2018 本日6日 14時間 $196
