Abstract
By controlling shapes of internal electrodes, when short-circuit occurs between the internal electrodes, a short-circuited portion may be opened by an overcurrent, to serve as a fuse. Also, by controlling shapes of internal electrodes, equivalent series inductance (ESL) at a high frequency may be reduced.
