FEATURES
• Six standard sizes
• High capacitance per unit volume
• Supplied in tape on reel or in bulk
case
• NiSn terminations.
APPLICATIONS
• Consumer electronics for example
− Tuners

• Data processing.
DESCRIPTION
The capacitor consists of a
rectangular block of ceramic
dielectric in which a number of
interleaved nickel electrodes are
contained. This structure gives rise
to a high capacitance per unit
volume.
The inner electrodes are connected
to the two copper terminations,
coated 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.
