One world. One KEMET
Overview
KEMET’s Ceramic Open Mode capacitor in X7R dielectric
is designed to signicantly minimize the probability of a
low IR or short circuit condition when forced to failure in
a board stress ex situation, thus reducing the potential
for catastrophic failure. The Open Mode capacitor may
experience a drop in capacitance; however, a short is
unlikely because a crack will not typically propagate
across counter electrodes within the device’s “active area.”
Since there will not be any current leakage associated
with a typical Open Mode ex crack, there is no localized
heating and therefore little chance for a catastrophic and
potentially costly failure event.
Driven by the demand for a more robust and reliable
component, the Open Mode capacitor was designed for
critical applications where higher operating temperatures
and mechanical stress are a concern. These capacitors
are widely used in automotive circuits as well as power
supplies (input and output lters) and general electronic
applications.
Concerned with ex cracks resulting from excessive
tensile and shear stresses produced during board exure
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 ex cracks which can result in low IR or short
circuit failures. Although exible termination technology
does not eliminate the potential for mechanical damage that
may propagate during extreme environmental and handling
conditions, it does provide superior ex performance over
standard termination systems. When combined with exible
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-CAP) and Floating Electrode with Flexible Termination
(FF-CAP) product lines by providing a fail-safe design
optimized for mid to high range capacitance values. These
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.
