Test Conditions
Solder Temperature 260°C ±5.0°C
Test Duration 10 seconds ±1 s
Performance Requirements:

Accelerated Pulse Handling Capability:
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.
Voltage Gradient Multiplier Test Cycles
6x 100
4x 1000
2x 1 million
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.
Performance Criteria After Testing
Capacitance Delta < 3%
ESR Absolute value < 150% of
original measured value

Type RBPS IGBT Snubber Capacitor Modules
Why Use Snubber Capacitors?
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.
Power systems containing IGBTs must be designed so
the transient voltages caused by the hi di/dt that occurs
at gate turn off is minimized. Left uncontrolled, this
transient voltage can exceed the blocking voltage rating
of the IGBT and cause it to fail. To reduce the tran-
sient voltage, either di/dt or the parasitic DC bus induc-
tance of the power circuit must be reduced. This is best
achieved by decoupling the parasitic bus inductance us-
ing a non-inductive wound lm capacitor mounted as
near as possible to the IGBT module terminals.
Snubber capacitors, constructed of polypropylene lm
dielectric and dual metallized lm electrodes, are the
optimal capacitor design for IGBT applications. While
lm/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
of metallized lm (not failing in a short circuit mode)
with the high peak current carrying capability (dv/dt) of
lm/foil construction.
Aerovox’s snubber capacitors, manufactured with poly-
propylene m and dual metallized electrodes, available
with direct IGBT module terminals, radial wire leads,
or a unique printed circuit board dual in-line pin mount,
provide the highest electrical performance of any snub-
ber capacitors currently available.
