I just found a part, that was not listed in the smd marking list. Maybe you'll like to add it.

I hope this will be useful

Please help me with the identification of these two smd components: SMR R540 1% C07cc and SMR R560 1% C07c. These outgoing components indicate 0 ohms in measurement, and when connecting to the circuit, I get 0 ohms between the base and the emitter at the MJE2955T and MJE3055T pairs of transistors. Thanks in advance!

Could someone identify this element?

There is only SF symbol marked on it. It is used to provide 3.4V from pin 5 to pin 6 going directly to msata SSD drive.

On pin 4 there is 0.3V when working.
