Surface Mount and Through-Hole Multilayer Ceramic Capacitors
KPS-MCL Low-Loss High Temperature 200°C SMPS Stacks,
200 – 2,000 VDC (Industrial Grade)
Overview
KEMET Power Solutions - Low loss (KPS MCL) High
Temperature SMPS Ceramic Stacked Capacitors combine
a robust and proprietary C0G/NPO base metal electrode
(BME) dielectric system with a durable lead-frame
technology for high temperature and high power SMPS
applications. These devices are specifically designed to
withstand the demands of harsh industrial environments
such as down-hole oil exploration and automotive/avionics
engine compartment circuitry.
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.
KEMET’s high temperature C0G capacitors are temperature-
compensating and are well suited for resonant circuit
applications, or for those where Q and stability of
capacitance characteristics are required. They exhibit no
change in capacitance with respect to time and voltage, and
boast a negligible change in capacitance with reference to
ambient temperature. Capacitance change is limited to ±30
ppm/ºC from −55°C to +200°C. In addition, these capacitors
exhibit high insulation resistance with low dissipation factor
at elevated temperatures up to +200°C. They also exhibit
low ESR at high frequencies and offer greater volumetric
efficiency over competitive high temperature BME ceramic
capacitor devices.
The KPS-MCL is constructed with large chip multilayer
ceramic capacitors (MLCCs), vertically stacked and
secured to a lead-frame termination system, using a high
melting point (HMP) solder alloy. Vertically stacking the
capacitors in lead frames allows for much lower ESR (low
loss) and thermal resistance, which translates to very
high ripple current capability. The lead-frame isolates
the MLCCs from the printed circuit board (PCB), while
establishing a parallel circuit configuration.
