GREENVILLE, SC -- Kemet Corp., a leading manufacturer of tantalum and ceramic capacitors, late Wednesday said Jeffrey A. Graves resigned as chief executive and as a director. No reason was made public.

The company tabbed James P. McClintock, president and chief operating officer, and David E. Gable, vice president and chief financial officer, to handle CEO responsibilities on an interim basis.

The board is actively seeking a new CEO.

Last week the company posted wider-than-expected losses of $38.9 million amid declining revenues and inventory problems.
