Surface Mount and Through-Hole Multilayer Ceramic Chip Stacked Capacitors
KPS MIL Series, SMPS Stacked Capacitors,
MIL–PRF–49470, DSCC 87106, 25 – 1,000 VDC
(Commerical, Military and 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.
Benefits
• −55°C to +125°C operating temperature range
• High frequency performance
• Bulk capacitance in a reduced footprint
• MIL–PRF–49470 QPL
• Military Case Codes 3, 4 and 5
• Space Grade available (“T” Level)
• DSCC approved (87106)
• Commercial/Industrial Grade available
• Customer specific requirements available
• Low ESR and ESL
• High thermal stability
• High ripple current capability
• Higher reliability than aluminum electrolytic or tantalum
• Available encapsulated or unencapsulated
Applications
• Military
• Space
• Industrial
• Input and output filtering on power supplies – often found
on “capacitor banks“
• Snubber circuits
• Radar filtering (28 V/microwave burst)
