Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
Open Mode Design (FO-CAP), X7R Dielectric, 16 – 200 VDC
(Commercial & Automotive Grade)
Overview
KEMET’s Ceramic Open Mode capacitor in X7R dielectric is
designed to significantly minimize the probability of a low IR or
short circuit condition when forced to failure in a board stress
flex situation, thus reducing the potential for catastrophic failure.
The Open Mode capacitor may experience a drop in capaci-
tance; however, a short is unlikely because a crack will not
mechanical damage that may propagate during extreme envi-
ronmental and handling conditions, it does provide superior flex
performance over standard termination systems. When combined
with flexible termination technology these devices offer the ultimate
level of protection against a low IR or short circuit condition. Open
Mode devices compliment KEMET's Floating Electrode (FE-
typically propagate across counter electrodes within the device’s CAP) and Floating Electrode with Flexible Termination (FF-CAP)
“active area.” Since there will not be any current leakage associ-
ated with a typical Open Mode flex crack, there is no localized
heating and therefore little chance for a catastrophic and poten-
tially costly failure event.
product lines by providing a fail-safe design optimized for mid to
high range capacitance values. These devices exhibit a predict-
able 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.
Driven by the demand for a more robust and reliable com-
ponent, the Open Mode capacitor was designed for critical
applications where higher operating temperatures and mechani-
cal stress are a concern. These capacitors are widely used in
automotive circuits as well as power supplies (input and output
filters) and general electronic applications.
Concerned with flex cracks resulting from excessive tensile
and shear stresses produced during board flexure and thermal
cycling? These devices are available with KEMET's Flexible
termination technology which inhibits the transfer of board
stress to the rigid ceramic body, therefore mitigating flex cracks
which can result in low IR or short circuit failures. Although flex-
ible termination technology does not eliminate the potential for
