Type KVx High-Voltage and Pulse, Mica-Paper/Polymer Capacitors
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 KVx capacitor. Jet engines roar
with KVx ignition capacitors. KVx will ignite your applications
with its high reliability, high energy density, high peak current
capability, and excellent mechanical properties.
Spanning voltages up to 150 kV, peak currents up to 100 kA, and
temperatures from -55 °C to +200 °C, Type KVx 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 KVx 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, exible reconstituted
mica paper, or a polymer lm/mica paper combination. Mica is
the proven reliable dielectric for high voltage and temperature
stress, even with continuous corona and radiation. We combine
mica synergistically with polymer lms to provide pulse
capacitors of extremely 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 capacitor element with
high temperature, heat-cured polyester tape and closes each
end with a thick poured section of epoxy. The nished 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 berglass epoxy tube.
Package Type M: For the ultimate in environmental protection
and operation up to 150 kV, the Type M package provides a fully
molded, vacuum-encapsulated system. The nal capacitor shape
can exactly meet your application mechanical requirements and
t where no other can.
Operating Life Guaranteed for 10 Years
KVx 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 KVx capacitors will operate ten
years or more when operated within specied limits. Cornell
Dubilier warrants that if KVx capacitor fails during normal
use within 10 years of the date of purchase, it will replace
the capacitor at no charge if CDE analysis conrms that the
capacitor was not abused by operating beyond product limits
for humidity, temperature, voltage, and current.

Capacitance Within Tolerance Capacitance is within tolerance when measured 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 Characteristic S –.5%, C –.05%
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 specication is available, to 0.1% for mica-plate capacitors, charac-
teristic C.
Life Test Subject capacitors to rated maximum temperature ±3 °C with rated volt-
age 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.
Leads Ribbon leads are typically tin-plated copper, 0.005” x 0.5”x2” on small
units (<1 in3) and 0.020” x 0.987” x 2” or larger.
Wire leads are typically bare AWG #18 or #20, 2” minimum.
Thread Studs Threaded studs or inserts are standard from 4-40 to 1⁄4-20 and typically
tin-plated brass.
Terminals Turret terminals are brass with silver or tinplate.
Connectors High voltage connectors are available with creepage, tracking and clear-
ance distances to meet requirements up to 150 kV.
Markings ID Marking includes manufacturer, CDM, capacitance in µF, rated voltage,
identication number and date code YYWW (2 digit year and week of
manufacture).
Life Test Vibration Resistance Subject the capacitors to simple harmonic motion with an amplitude of
0.06 inches; vary the frequency uniformly 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 dam-
age, 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.
Withstand 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 uid when needed to prevent external arcing.
Look up the test voltage as a multiple of the Rated Voltage below:
Rated Voltage T est Voltage Rated Voltage T est 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%
Moisture Resistance Moisture Resistance: Subject G or M package capacitors to 40 ±2 °C at 90
to 95% humidity for 500 (+24, –0) hours. Return to room ambient for 24
hours. There will be no visual damage, the capacitance will not change
more than the greater of ±4% or 1 pF, and the insulation resistance will be
no less than the lesser of 7.5 GΩ and 5 GΩµF. Moisture resistance is not
specied for T package capacitors and product warranty is void if used
regularly beyond 50% relative humidity.

Order by complete Part Number. For capacitors with special requirements we will assign you a new number at
order entry. Use Outline Drawings and Typical Ratings as a capability guide. They are for mica-paper capacitors
in Type T packages with S characteristic. Standard leads are AWG #18 centered on the ends for less than 20
kVdc and oset as shown for 20 kVdc and up. See Terminations for optional leads and terminals. We invite you
to challenge us with your special requirements for high-voltage and pulse capacitors. Also feel free to request
custom shapes for G and M package units. Those packages can deliver unique shapes and congurations and
are not limited to the simple, rectangular shapes shown here.
Part Numbering System
Temperature Coecient 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
temperature coecient 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 eects of the dielectric.For rep-
etition-rated applications, use double the dc rating in the Typical Ratings
table on the following page. In other words, for a 10 kV repetition-rated
capacitor applicaiton, use a 20 kVdc rated capacitor.
The Ratings table on the next page lists maximum pulse repetition
frequency (PRF) and maximum peak current (IPEAK) at the maximum PRF
at room temperature 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 derating, contact us for alternatives. Also we can recom-
mend active cooling strategies for your high energy density application.
