Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
KPS Series, X7R Dielectric, 10 – 250 VDC (Commercial Grade)
Overview
KEMET Power Solutions (KPS) Commercial Series stacked
capacitors utilize a proprietary lead-frame technology
to vertically stack one or two multilayer ceramic chip
capacitors into a single compact surface mount package.
The attached lead-frame mechanically isolates the
capacitor/s from the printed circuit board, therefore offering
advanced mechanical and thermal stress performance.
Isolation also addresses concerns for audible, microphonic
noise that may occur when a bias voltage is applied. A
two chip stack offers up to double the capacitance in
the same or smaller design footprint when compared to
traditional surface mount MLCCs devices. Providing up
to 10 mm of board flex capability, KPS Series capacitors
are environmentally friendly and in compliance with RoHS
legislation. Available in X7R dielectric, these devices are
capable of Pb-Free reflow profiles and provide lower ESR, ESL
and higher ripple current capability when compared to other
dielectric solutions.
Combined with the stability of an X7R dielectric, KEMET’s
KPS Series devices exhibit a predictable change in
capacitance with respect to time and voltage and boast a
minimal change in capacitance with reference to ambient
temperature. Capacitance change is limited to ±15% from
−55°C to +125°C.

Regarding Aging Rate: Capacitance measurements (including tolerance) are indexed to a referee time of 48 or 1,000 hours. Please refer to a part
number specific datasheet for referee time details.
2
DWV is the voltage a capacitor can withstand (survive) for a short period of time. It exceeds the nominal and continuous working voltage of the
capacitor.
3
Capacitance and dissipation factor (DF) measured under the following conditions:
1 kHz ±50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 µF
120 Hz ±10 Hz and 0.5 ±0.1 Vrms if capacitance > 10 µF
4
To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known
as Automatic Level Control (ALC). The ALC feature should be switched to "ON."
