DESCRIPTION
The capacitor consists of a
rectangularblockofceramicdielectric
in which a number of interleaved
nickel electrodes are contained.
This structure gives rise to a high
capacitance per unit volume.
Theinnerelectrodesareconnectedto
the two terminations by a
copper-dipped layer and finally
covered with a layer of plated
nickel/tin (NiSn).
A cross section of the structure is
shown in Fig.1.
