Hi, for what I can see the broken Chip is placed on the +V line on the pin 8 of the operational LM358.
This Chip is for cleaning the +V. To know the exact value I should unsolder the Chip on a working board take a measure of it and resolder it back. It' a little bit complicated.

Fortunately I've a little bit of experience ;) in this field and I think the correct Value can be 100nF SMD ceramic Capacitor.
Try this value and let me know.

Be Aware: before changing the chip you have to spot the cause that make the chip blowing out !! This blowing is caused by a Short somewhere in your board.

In the picture I can see a Voltage regulator near the blowed capacitor. I think you have to investigate there because maybe it's in short circuit.

Let me know.
Bye
