The KEMET Flexible Termination (FT-CAP) multilayer
ceramic capacitor in X7R dielectric incorporates a unique,
flexible termination system that is integrated with the
KEMET standard termination materials. A conductive silver
epoxy is utilized between the base metal and nickel barrier
layers of KEMETs standard termination system in order
to establish pliability, while maintaining terminal strength,
solderability and electrical performance. This technology
was developed in order to 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. Flexible termination
technology 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 this technology does not eliminate the potential
for mechanical damage that may propagate during extreme
environmental and handling conditions, it does provide
superior flex performance over standard termination
systems. FT-CAP complements the KEMET Open Mode,
Floating Electrode (FE-CAP), Floating Electrode with
Flexible Termination (FF-CAP) and KEMET Power Solutions
(KPS) product lines by providing a complete portfolio of flex
mitigation solutions.
Combined with the stability of an X7R dielectric and designed
to accommodate all capacitance requirements, these flexrobust devices are RoHS-compliant, offer up to 5 mm of
flex-bend capability and exhibit a predictable change in
capacitance with respect to time and voltage. Capacitance
change with reference to ambient temperature is limited to
15% from ˆ’55°C to +125°C.
Dimensions: 1.6 x 0.8 x 0.8 mm
