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, either by silver
palladium (AgPd) alloy in the ratio
65 : 35, or 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.
