I have made a list of SMD components found on Flight controllers, ESCs and other RC electronics. Here you can find component markings, basic specifications and some other info. Also a link for quick source of the part is provided.
This might be useful for any RC enthusiast, who can or want to replace/repair the electronic devices.
Please feel free to write a comment if you want to ask for any component identification.
Voltage regulators
Linear regulators
Most widely used for stepping down the supplied +5V voltage to +3.3V for digital logic IC’s.

Switching regulators
Usually they are used where a high current power supply is needed. They are used on flight controllers, some ESCs, VTX and a number of other FPV components to step down from battery voltage to the 10V/9V/5V, providing a large current supply. The most often they step down from battery voltage to +5V.

| SCT2650 | SCT 2650 | 4.5V-60V Vin, 5A High Efficiency Step-down DCDC Converter | Matek PDB |  | LCSC Aliexpress |
Mosfet, FET, PowerFET
Power MOSFETs found on ESC, 4in1 ESC are driving the motors – switching rapidly on/off the current to the motor windings.
Usually the MOSFET should be max current rated at least 30% more than ESC rating.
