Kekon high voltage capacitors
are designed
according to international specification IEC (or to EIA) as
the ultrastable CG, known as NP0 (C0G) and
the stable 2R1 (X7R)
NP0 dielectric is made of ceramic materials which are not
ferroelectric.
The NP0 capacitors are used in applicationswhich require
very stable characteristics with no dependence of capacitance
and dissipation factor (tand) on time, voltage and frequency. This yields a superior
stability characteristic, but relatively low capacitance. Stable 2R1
(X7R) capacitors are made from ferroelectric materials, principally barium titanate.
High voltage capacitors are specially designed for high voltage applications,
such as:
DC-DC converters
Voltage multipliers
Radio and TV receiver
Modems
Interfaces
Other electrical appliances where
high voltage is present
