FEATURES
•
Sizes 1206; 1808; 1812
•
High capacitance per unit volume
•
Supplied in tape on reel or in bulk
•
NiSn terminations.
APPLICATIONS
These surface mounted high voltage
capacitors were developed
specifically for circuits requiring
voltage of 1 kV to 2 kV. Typical
applications are:
•
Inverter circuits for the backlights
of liquid crystal displays
•
Snubber circuits of power
supplies
•
Voltage multiplier circuits and
circuits where surge protection is
required.
Due to high voltage across the
terminations, circuit applications of
1 kV or higher may need a coating
on the surface to prevent external
arcing. This is especially true under
humid conditions.

terminations
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, finally
covered with a layer of plated tin
(NiSn). A cross section of the
structure is shown in Fig.1.
