Multi Mini Capacitor MMC

Today I started on the MMC (multi mini capacitor). The capacitors had arrived from Teslastuff.com a few weeks earlier. The MMC is built up of 40 capacitors, 2 banks of 20 caps in series connected in parallel. Each capacitor is rated at 0.15uf at 2000v as per the original Teslastuff plans.






A bag of 20 capacitors for the first layer of the MMC. This layer would be mounted on a 8mm thick 320mm by 220mm clear perspex board.







The board was covered in masking tape and marked out for drilling.I drilled 1.75mm holes for the cap legs (40 in total), some 4mm holes for mounting onto 1" ceramic stand-offs and 2 6mm holes for the copper lugs. After marking out I attached an identical piece of perspex to the back so I could drill both layers at the same time.







After drilling I mounted the 20 caps to the first level. I twisted the adjacent caps legs together and then laid the bleed capacitors across each cap before soldering.







Also soldered in some copper wire to create the series links between the rows and a couple of terminal loops on the ends.







Above is the first layer completed. The 5 support uprights are 12mm diameter perspex drilled and tapped to accept 4mm bolts. Now for the second layer.






The finished article.






Very pleased with the end result.






Will also be easy to add more layers in the future.
