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.
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. 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.
