This is mainly to see the chip (IC) model, C2 may be a small series to which it belongs, it seems that there is no C2 such an IC (integrated circuit) model alone, 5-pin IC a lot, mostly for power management IC, which is mainly to find out which part of the circuit it is located on the circuit board, so that you can guess.
