marke Posted September 20, 2008 Report Share Posted September 20, 2008 Hello ram It really depends on what you want to do with this figure. Different manufacturers have different definitions, but you would not be too far out if you took the time off the thermal curve at 600% current. I would use the cold curve. Best regards, Mark.
