Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
Floating Electrode Design with Flexible Termination
System (FF-CAP), X7R Dielectric, 6.3 – 250 VDC
(Commercial & Automotive Grade)
Overview
KEMET’s Floating Electrode with Flexible Termination
capacitor (FF-CAP) combines two existing KEMET
technologies– Floating Electrode and Flexible Termination.
The floating electrode component utilizes a cascading
internal electrode design configured to form multiple
capacitors in series within a single monolithic structure.
This unique configuration results in enhanced voltage and
ESD performance over standard capacitor designs while
allowing for a fail-open condition if mechanically damaged
(cracked). The flexible termination component utilizes a
conductive silver epoxy between the base metal and nickel
barrier layers of KEMET’s standard termination system
in order to establish pliability while maintaining terminal
strength, solderability and electrical performance. Both
technologies address the primary failure mode of MLCCs–
flex cracks, which are typically the result of excessive
tensile and shear stresses produced during board flexure
and thermal cycling.
The FF-CAP complements KEMET’s Open Mode, Floating
Electrode (FE-CAP), Flexible Termination (FT-CAP) and KEMET
Power Solutions (KPS) product lines by providing an ultimate
fail-safe design optimized for low to mid 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.
In addition to Commercial Grade, Automotive Grade devices
are available which meet the demanding Automotive
Electronics Council's AEC–Q200 qualification requirements.
Although neither technology can eliminate the potential for
mechanical damage that may propagate during extreme
environmental and/or handling conditions, the combination
of these two technologies provide the ultimate level of
protection against a low IR or short circuit condition.
