Is there a power supply at the capacitor interface
What is the main purpose of bulk input capacitors in a power supply ...
The main purpose of bulk capacitors on the input of a design is to control input spikes when there is an output current transient. It is important to keep in mind that when there is an output load transient this energy must come from the input of the regulator.

For the receiver end, it is strongly recommended to route the trace from the BGA pad to the capacitor pad on the top layer. This avoids a via escape between the BGA pad and the capacitor. This style of connection is possible on Serial RapidIO ports and the SGMII port. On the other side of the capacitor, it is recommended to via to another layer.

Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …

I''m looking at this design For a split supply. I get that the thermistors are there to limit the inrush current, but I don''t understand the purpose of C9 and how its value was chosen. In addition to Autistic''s correct answer, the value of C9 (X rated) is a compromise between consuming excessive AC current at 60 Hz while suppressing the …
