Surface Mount & Through-Hole Multilayer Ceramic Chip Stacked Capacitors
KPS MIL Series, SMPS Stacked Capacitors, MIL-PRF-49470,
DSCC 87106, 50VDC–500VDC (Commercial, Military, & Space Grades)
Overview
KEMET Power Solutions (KPS) MIL Series ceramic stacked
capacitors are available in commercial, military and space grades
and are well suited for standard and high reliability switch mode
power supply (SMPS) and pulse energy applications. Qualified
under performance specification MIL-PRF-49470, our military and
space grade products meet or exceed the requirements outlined
by DSCC (Defense Supply Center, Columbus) and are available
in both B (standard reliability) & T (high reliability) product levels.
MIL-PRF-49470 was developed as part of a cooperative effort
between the U.S. Military, NASA and SMPS suppliers to produce
a robust replacement to cancelled DSCC Drawing 87106.
The KPS MIL Series is constructed using large chip multilayer
ceramic capacitors (MLCCs), horizontally stacked and secured
to a lead-frame termination system using a high melting point
(HMP) solder alloy. The lead frame isolates the MLCCs from the
printed circuit board (PCB) while establishing a parallel circuit
configuration. Mechanically isolating the capacitors from the PCB
improves mechanical and thermal stress performance, while the
parallel circuit configuration allows for bulk capacitance in the
same or smaller design footprint.
Available in BX, BR, BQ, and X7R dielectrics, these devices
are available in encapsulated and unencapsulated styles
in both surface mountable and through-hole configurations.
Their low Equivalent Series Resistance (ESR) and Equivalent
Series Inductance (ESL) make them ideally suited for input and
output filtering of power supply as well as snubber applications.
The encapsulated styles are primarily used where increased
mechanical and environmental protection is required, such as in
avionics systems.

Ordering Information Requirements per DSCC Drawing 87106
DSCC Drawing 87106 was cancelled on 01/03/2005. Customers can continue to order per 87106 requirements using the original DSCC ordering code,i.e., 87106-001.
When available, MIL-PRF-49470 devices are preferred over DSCC Drawing 87106. The MIL-PRF-49470 military specification product provides additional quality
assurance provisions that are not required by the DSCC drawing. These extra provisions create a more robust replacement.
