                        C1812C334K5RAC / C1812C105K5RAC PART FAILURES

                        Please put me in contact with someone who can
discuss possible mechanical failures of the above listed Kemet capacitors.
We have had several electrical failures with the above parts and think it
could be due to physical stress on the parts. Please contact me if you have
any data on this possible problem with the 1812 package.

                        Spoke with Jim Beaumont at Kemet in Orlando this AM.
He's working on getting us further info on these failure modes.



                        We have had trouble with the above parts but have no
idea as to what our problem is at this time. They are supposed to get back
with us. We would be interested to know if others have had problems with
these footprint sizes (1812).

                        thanks

                                Subject:        [TN] Chip Capacitors

                                Hi all,

                                I would like to hear from anyone who can
estimate their manufacturing
                                yield impact due to failure of chip
capacitors, i.e. due to cracks,
                                leakage, etc.  I have been doing failure
analysis on these types of part
                                issues and I am trying to benchmark expected
yield and/or failure rates
                                under "normal" conditions.

                                Any help would be sincerely appreciated!

                                Best Regards,
                                Ed Hare
