2003 Jul 18 Rev.7 2 www.yageo.com
FEATURES
• Five standard sizes
• High capacitance per unit volume
• Supplied in bulk case or in tape
on reel.
APPLICATIONS
• Consumer electronics
• Telecommunications
• Automotive
• Data processing.
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.
