Ceramic Capacitors FAQQAre there any precautions for board design when considering a switch to small (0201 inch size, etc.) chip multilayer ceramic capacitors?


Due to the increased risk of cracking caused by board bending, caution is required when switching from a 0603 inch size or larger capacitor to a 0402 inch size or 0201 inch size and changing only the land size.

An explanation of the mechanism behind the risk increase and the measures to take for safe use are summarized in the following document.
