For example, the Tekin R1/RS ESC is rated for 104A when using the Ta 25C 26A rating and 76A when using the Ta 85C 19A rating of the On Semi NTMFS4833N. Now if I use he Tc 25C 191A rating the ESC would be a 764A and the Tc 85C 138A rating it would a 552A, but here is where things get interesting. The NTMFS4833N has a Pulse current of 288A which would give you a 1152A rating. How did I get those numbers you ask? Simple, the R1/RS uses 8 MOSFETs per phase, but I only multiplied the AMP number by 4 due to the H bridge design of a brushless ESC. Now the R1/RS has a total of 24 MOSFETs. If it's possible to get the part number for the MOSFET you use in your Kinetic ESC, we could come up with a better rating for it. Will it be less then the 540A rating yes, but I would respect the true rating more then the 540A out of the blue rating.

BTW, we are still waiting for an explanation on how Novak came up with the 540A rating.
For more info, email Bob.
