KEMET is now on the QPL list for Switch Mode
Power Supply (SMPS) Military Stacked Capacitors
with MIL-PRF-49470 standard B Level reliability
availability. These devices are intended for high
reliability SMPS and pulse energy applications.
Their low Equivalent Series Resistance (ESR) and
Equivalent Series Inductance (ESL) make them ide-
ally suited for input and output filtering of power sup-
ply applications as well as snubber applications.
The multilayer construction also creates high ther-
mal transfer functions, resulting in very little temper-
ature rise for the generated power giving the capac-
itors excellent high current handling capability.
The performance benefits of ceramic are being
realized in many applications that were heretofore
unavailable to these capacitors. The replacement
of larger capacitance electrolytic capacitors with
smaller value ceramics is a common occurrence
today, but there are still some larger capacitance
values required of the MLCC.
The capacitors are constructed using large chip
sizes, much larger than those available for standard
surface-mount applications. Because they are so
large, mounting these devices directly to the PC
board would more than likely generate cracking
because of straight mechanical strain, or strain
which occurs because of mismatches in CTE (coeffi-
cient of thermal expansion) between the board and
the ceramic.
This strain is proportional to the distance be-
tween the termination pads on the PC board and
results in an increasing propensity for failure
among the larger SMT chips. The leadframe is
attached to the chip stack (from singular to multiple
chips) and creates a mechanical relief between the
ceramic device and the board, so they are not
bound to each other. The contact to the chips is
usually a perforated, vertical, metal plate while the
contact to the board is through a pin structure.
The pin structure located at the bottom of the lead-
frame consists of multiple pins at 100 mil centers.
The formation of these pins can be surface mount-
able styles "L" and "J" (or gull-wing), or as through-
hole insertion pins style "N."
This multi-pin arrangement allows the
extremely low ESR and ESL of the chip package
to be presented to the circuit without any signifi-
cant increases. This arrangement also allows a
very efficient thermal transfer path to exist
between the chip package and the PC board, as
most of the thermal dissipation for this package
will be through the leadframe connection.
These capacitors are available in case codes
3, 4, & 5. They are available in X7R dielectric, in
voltage ranges from 50 VDC to 500 VDC. The
chip stack is horizontal and the leadframe attach-
ment is a high-temperature solder. They are also
available as unpotted bare chips or as a potted
assembly. MIL-PRF-49470 and DSCC drawing
87106 (X7R) are used to establish a baseline part
for high-reliability applications.
Capacitance values at 50 VDC are available
up to 47 μF (X7R). Care must be exercised when
using the bare chips to ensure there can be no
mechanical damage imposed on the mounted
parts, although the potted devices reduce this
potential dramatically.
Larger Case codes 1, 2, & 6 will be available
for order in Q3CY08. The T level high reliability
space level version will be available in calendar
year 2009.

KEMET is qualified to supply MIL-PRF-
49470/1 unencapsulated X7R Case Codes 3, 4, &
5 ceramic SMPS capacitors in voltage ratings 50V,
100V, 200V, and 500V. KEMET is also qualified to
supply MIL-PRF-49470/2 encapsulated X7R Case
Codes 3, 4, & 5 ceramic SMPS capacitors in volt-
age ratings 50V, 100V, 200V, and 500V.
The DSCC drawing 87106 has been cancelled
(http://www.dscc.dla.mil/Downloads/
MilSpec/DsccDwg/87106.pdf). However, KEMET
is able to supply to the DSCC 87106 drawing per
customer request. KEMET will supply to the
DSCC 87106 drawing with an exception taken to
performing Group B Inspections on a per lot basis.
Per DSCC drawing section 4.2.2 the acquiring
activity, at its discretion, may accept a certificate of
compliance (CofC) with Group B inspections in
lieu of performing Group B inspections. KEMET
87106 orders will include the CofC stating compli-
ance to the 87106 requirements. KEMET's MIL-
PRF-49470 QPL status confirms KEMET's compli-
ance to the Group B testing requirements.
The MIL-PRF-49470 capacitors are preferred
over the DSCC drawing 87106 capacitors as out-
lined in NASA's Electronic Parts and Packaging
website:http://nepp.nasa.gov/npsl/Capacitors/
87106/87106aps.htm. The M49470 military spec-
ification product provides additional quality assur-
ance provisions that are not required by the DSCC
drawing. These extra provisions helped to create a
more robust replacement for the 87106 capacitors.

APPLICATION NOTES FOR MIL-PRF-49470
Note: DSCC-DWG-87106 for similarly constructed parts was CANCELED Jan 2005.
Use MIL-PRF-49470 parts as a direct replacement.
When available MIL-PRF-49470 SMPS capacitors are preferred over DSCC-DWG-87106 capacitors. The
MIL-PRF-49470 specification was developed as part of a cooperative effort amongst the US Military, NASA
and the SMPS suppliers to produce a robust replacement for the DSCC drawing. The MIL spec product pro-
vides additional quality assurance provisions which are NOT required by the DSCC drawing. Some of the ben-
efits of the MIL-PRF-49470 product over the DSCC-DWG-87106 product include:
Requirement MIL-PRF-49470 DSCC-DWG-87106
Formal Qualification Process (QPL Established) Yes No
MIL-STD-790 Compliance Yes No
DSCC Audits Yes No
Routine Qualification Maintenance Testing (ie.,
Life Testing) Yes No
Group A Percent Defective Allowed (PDA)
Specified Yes No
Prohibits Mixing of Chips from Different
Production Lots within a Single SMPS Stack Lot Yes No
SOLDERING RECOMMENDATIONS FOR CERAMIC STACKED CAPACITORS
Ceramic stacked capacitors are large mass devices and much care should be taken when soldering these
capacitors. For this reason, hand soldering is not a recommended soldering method for these devices.
Following the proper soldering guidelines is critical in order to prevent thermal cracking.
PRE-HEATING AND REFLOW PROFILE
Due to differences in the coefficient of thermal expansion for the different materials of construction it is critical
to monitor and control the heating and cooling rates during the soldering process. During the reflow soldering
process, the maximum recommended heating and cooling rate (dT/dt) is 4°C/second. To ensure optimal com-
ponent reliability, KEMET's recommended heating and cooling rate is =2°C/second. After soldering, the capac-
itors should be air cooled to room temperature before further processing. Forced air cooling is not recom-
mended.
