The following text outlines many of the common and less common reasons for
cracking capacitors. The problem is less common today but has always been a
issue in industry.

Subject: [TN] Ceramic caps
Hi TechNeters,
I came across an unusual (at least to me) failure mode of ceramic caps.
They crack along the component body in either normal (from top all the
way through to the bottom), or parallel (from one side all the way
through to the other side) direction to the board the caps are mounted
on.
Has anyone seen something similar?
Thanks a lot in advance.
Regards,
Vladimir
