resin.
Marking:

Test Conditions:
A capacitor under test will be charged through an
impedance of a magnitude greater than the discharging
impedance. The capacitor under test will be charged to
the rated DC voltage and discharged through an imped-
ance capable of producing a minimum voltage gradi-
ent with time (DV/DT). The test will be performed in
accordance with the requirements for the voltage
gradient multiplier and charge and discharge cycles as
listed below.

Example:
An RBPS part rated 1.0 uF 1,000 VDC has a DV/DT
rating of 600 volts per microsecond. This part would
be capable of withstanding 100 cycles at a minimum
of 3,600 volts/microsecond, 1000 cycles at 2,400 volts/
microsecond, or 1 million cycles at 1,200 volts/micro-
second.

Why Use Snubber Capacitors?
®
RoHS Compliant
Type RBPS IGBT Snubber Capacitor Modules
With the evolution of power technology, new higher
speed Insulated Gate Bipolar Transistors (IGBTs) make
it possible for high power converters to operate up to 10
kHz or more. IGBTs are replacing the slower Darling-
ton transistors, simplifying circuit design and reducing
cost. IGBT power modules are now being designed
into AC and DC motor drive inverters, uninterruptible
power systems, electric vehicles and alternate energy
production systems.
Snubber capacitors, constructed of polypropylene film
dielectric and dual metallized film electrodes, are the
optimal capacitor design for IGBT applications. While
film/foil capacitors are often used because of their su-
perior current carrying capability, they fail in a short
circuit mode, which may cause damage to the IGBT
module. Aerovox’s snubber capacitors combine high
current carrying capability with low inductance, low
dielectric losses and capacitance stability across a wide
frequency range. They offer the self-healing property
Power systems containing IGBTs must be designed so
of metallized film (not failing in a short circuit mode)
the transient voltages caused by the hi di/dt that occurs with the high peak current carrying capability (dv/dt) of
at gate turn off is minimized. Left uncontrolled, this
film/foil construction.
transient voltage can exceed the blocking voltage rating
of the IGBT and cause it to fail. To reduce the tran- Aerovox’s snubber capacitors, manufactured with poly-
sient voltage, either di/dt or the parasitic DC bus induc-
propylene fim and dual metallized electrodes, available
tance of the power circuit must be reduced. This is best with direct IGBT module terminals, radial wire leads,
achieved by decoupling the parasitic bus inductance us- or a unique printed circuit board dual in-line pin mount,
