KVx High-Voltage and Pulse Capacitors Ignite Your World
Voltage, Current and Temperature to New Heights
KaBOOM! Another exploding foil initiator successfully
detonates a military smart bomb thanks to a KV
x
capaci-
tor.
Jet engines roar with KV
x
ignition capacitors. KV
x
will
ignite your applications with its high reliability, high
energy density, high peak current capability, and excel-
lent mechanical properties.
Spanning voltages up to 150kV, peak currents up to
100kA, and temperatures from -65°C to +200°C, Type KV
x
capacitors are it for applications like pulse ignition,
corona-free signal coupling, high-voltage energy storage
and voltage division of high AC voltages.
Wide Selection of Capabilities
The Type KV
x
capacitor draws on an unprecendented
selection of three dielectric systems, three impregnating
systems, and three package types to deliver its superior
capabilities.
The dielectric is high-purity mica plates, flexible reconsti-
tuted mica paper, or a polymer film/mica paper combi-
nation. Mica is the proven reliable dielectric for high
voltage and temperature stress, even with continuous
corona and radiation. We combine mica synergistically
with polymer films to provide pulse capacitors of ex-
tremely high energy density (to over .1 J/cc).
High value with three impregnation systems: Epoxy—for
best value operation through 125°C; Polyester Resin—
for continuous operation up to 200°C.
Five Package Types Deliver Custom Fit
Package Type B: Bare sections-if you want to design
your own package.
Package Type C: Metal Can-to be worked out individually.
Package Type T: For minimum size and quick avail-
ability, the Type T package wraps the rectangular capaci-
tor element with high temperature, heat-cured polyester
tape and closes each end with a thick poured section of
epoxy. The finished capacitor is sealed and is suitable for
potted-in and many low humidity applications.
Package Type G: In applications requiring superior
mechanical integrity, such as metal clamp mounting,
moisture exposure, and mechanical vibration and shock,
the Type G package adds that needed strength by
vacuum potting the capacitor element in a laminated
fiberglass epoxy tube.
Package Type M: For the ultimate in environmental
protection and operation up to 150kV, the Type M package
provides a fully molded, vacuum-encapsulated system. The
final capacitor shape can exactly meet your application
mechanical requirements and fit where no other can.
Operating Life Guaranteed for 10 Years
KV
x
capacitors are not ordinary high voltage capacitors.
Manufacturing processes developed and proven over 50
years of continuous manufacture of transmitting, pulse
and high-voltage capacitors allow us to make a remark-
able guarantee. Cornell Dubilier guarantees that KV
x
capacitors will operate ten years or more when operated
within specified limits. Cornell Dubilier warrants that if a
KV
x
capacitor fails during normal use within 10 years of
the date of purchase, it will replace the capacitor at no
charge if CDE analysis confirms that the capacitor was
not abused by operating beyond product limits for
humidity, temperature, voltage, and current.

Ribbon leads are typically tin-plated copper,
0.005”x0.5”x2” on small units (<1 in
3
) and
0.020”x0.987”x2” on larger.
Wire leads are typically bare AWG #18 or
#20, 2” minimum.
Threaded studs or inserts are standard from
4-40 to
1
⁄4-20 and typically tin-plated brass.
Turret terminals are brass with silver or tin
plate.
High voltage connectors are available with
creepage, tracking and clearance distances to
meet requirements up to 150 kV.
ID Marking includes manufacturer, CDM,
capacitance in µF, rated voltage, identification
number and date code YYWW (2 digit year and
week of manufacture).
Capacitance is within tolerance when mea-
sured at 1 kHz (1 MHz if C<1000 pF). Standard
tolerance:
±5%≥10 kV
±10%≥100 pF & 5 kV
±20%<100 pF & 5 kV
Dissipation Factor is no more than 0.5%, S
characteristic, when measured at 1 kHz (1 MHz if
C<1000 pF) and room temperature. Lower dissi-
pation factor specification is available, to 0.1%
for mica-plate capacitors, characteristic C.
Insulation Resistance is no less than the
lesser of 100 GΩ and 5 GΩµF, when measured
at 500 Vdc after 2 minutes, and at room tem-
perature (1 GΩ or 25 MΩµF at 125°C).
Rated Voltage is the maximum peak voltage
for actual use.
Withstanding Voltage: Apply a DC test
voltage for 5 seconds with the charge and
discharge current limited to one ampere and
with the capacitor immersed in an insulating
fluid when needed to prevent external arcing.
Look up the test voltage as a multiple of the
Rated Voltage in this table:
Rated Voltage Test Voltage
0 to 8 kV 200%
8.1 to 10 kV 175%
10.1 to 12 kV 150%
12.1 to 20 kV 140%
20.1 to 30 kV 130%
30.1 kV and up 120%
Corona-Free capacitors are readily available
and certification for corona-free operation up
to 50 kVac or kVdc is available.
Life Test: Subject capacitors to rated maxi-
mum temperature ±3°C with rated voltage
applied for 2000(+72,-2)hours. There will be no
visual damage and the capacitance will not
have changed more than the greater of ±3%
and ±1 pF.
Vibration Resistance: Subject the capaci-
tors to simple harmonic motion with an ampli-
tude of 0.06 inches; vary the frequency uni-
formly from 10 to 55 Hz and return to 10 Hz, all
in one minute. Repeat that cycle continuously
for 2 hours in each of 3 mutually perpendicular
directions. There will be no visual damage, the
capacitance will not change more than the
greater of ±3% and ±1 pF, and the insulation
resistance will be no less than the lesser of 7.5
GΩ and 5 GΩµF.
Moisture Resistance: Subject G or M pack-
age capacitors to 40±2°C at 90 to 95% humid-
ity for 500(+24,-0)hours. Return to room ambi-
ent for 24 hours. There will be no visual dam-
age, the capacitance will not change more
than the greater of ±4% or 1 pF, and the
insulation resis-
tance will be no less
than the lesser of
7.5 GΩ and 5
GΩµF.
Moisture resis-
tance is not speci-
fied for T package
capacitors and
product warranty
is void if used regu-
larly beyond 50%
relative humidity.
Temperature
Coefficient and
Drift: Measure
the
capacitor’s capacitance at 25°C, -55°C, 25°C,
125°C, and at 25°C…all ±3°C…after stabilizing
at each temperature. The capacitance tem-
perature coefficient will be less than or equal to
±500 ppm/°C, and the capacitance will not
have changed more than ±(0.5%+0.1 pF).
Pulse Capability: Maximum achievable peak
current is usually limited by the inductance of
the discharge circuit, not by rise-time effects of
the dielectric.
For repetition-rated applications, use double
the dc rating in the Typical Ratings table on
the following page. In other words, for a 10kV
repetition-rated capacitor applicaiton, use a
20 kVdc rated capacitor.
The table of Typical Ratings on the follow-
ing page lists maximum pulse repetition fre-
quency (PRF) and maximum peak current
(I
PEAK
) at the maximum PRF at room tempera-
ture ambient conditions. To use higher peak
current, derate the PRF as the square of the
peak current ratio. For example, to use double
the maximum rated peak current, use one-
quarter of the maximum rated repetition rate.
For higher rep rate applications, or to enable
higher peak current without the above derat-
ing, contact us for alternatives. Also we can
recommend active cooling strategies for your
high energy density application.
Capacitor Size is determined by your choice
of package, the capacitance and the rated
voltage. For new designs, we will furnish your
capacitor’s size with our quotation. For a first
estimate of capacitor size refer to the Typical
Ratings table page 46.
