As my video shows , I put 1.12A (from 1 li-ion cell with 3Ohm resistor) into FET and measure 3.3mV at pins close to FET body, and 4mV at end of pin (only one pin has 0.5mOm resistanse). temps around is 30Â°C.
I do not have another type of 4110 for tests.
Sorry, I gave up trying to interpret the test conditions in the video as soon as I realized I couldn't speak the language.
As liveforphysics mentioned, you need much higher current levels to calculate the on-state resistance accurately, at least 10A IMHO.
A 20A test would be nice too.
