DESCRIPTION
The capacitor consists of a
rectangular block of ceramic
dielectric in which a number of
interleaved precious metal
electrodes are contained. This
structure gives rise to a high
capacitance per unit volume.
The inner electrodes are connected
to the two terminations, silver dipped
with a barrier layer of plated nickel
and finally covered with a layer of
plated tin (NiSn). A cross section of
the structure is shown in Fig.1.
