Question about the power input capacitor of this circuit [Copy link]

In the following circuit, xdm, why does the power input capacitor in this application case use a ceramic capacitor?

呜呼哀哉

One of the main reasons is the size. It is getting smaller and smaller all the time, and we are getting less and less skilled at it.

Are there any problems with using ceramic capacitors?

You can look at the impedance frequency curve in its datasheet

Maybe it's because of its small size and low price.

Alas, published on 2023-4-19 10:51 The main reason is the size. Now it is getting smaller and smaller.

Just because it’s small?

Not completely agree

Excuse me

How to interpret the switching frequency and resistance relationship diagram from the following figures?

Ceramic capacitors have the advantages of fast high-frequency response, small size, high temperature resistance, low distortion and low price, especially low price.

It's just a consideration of size and cost, but it's impossible to tell without front-end power information.
