Component choice and Swap

[chrischina]

I have two questions in one:

I have collected some schematic from datasheet from manufacturer of chip. Inside the datasheet there are the following circuit shown below.

1./ The manufacturer don't provide the BOM, so I don't have part number for all those small passive components. How to decide which one to use in terms of tolerance, X5R/X7R, Voltage, package ?

2./ On some schematic there are some polarized capacit, typically some round cylinder space consumming. By what type of SMD can I replace those big cylinder to make the circuit smaller ?

While answering this question, please explain it so I can understand what logical methodology you are using





Thank you
