Hello Naizeng

No you cannot use 100nF. Please use 2.2nF.

Hi EL,

What's the reason that we cannot use 100nF? Could you elaborate it technically?

Hello Naizeng

Operation outside the Absolute Maximum Ratings may cause a permanent damage to the device. I am not allowed to disclose more details which are not public.
