Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
X7R with KONNEKT™ Technology, 25 – 3,000 VDC
(Commercial & Automotive Grade)
Lead-free
Overview
Capacitance change is limited to ±15% from −55°C to
KEMET's X7R with KONNEKT™ technology surface mount
capacitors are designed for applications where higher
capacitance and voltage are needed without requiring
additional board space. KONNEKT high density packaging
technology uses an innovative Transient Liquid Phase
Sintering (TLPS) material to create a surface mount multi-
chip solution for high density packaging.
+125°C.
In addition to their use in power supplies, these capacitors
can be used in industries related to automotive (hybrid),
telecommunications, medical, military, aerospace,
semiconductors and test/diagnostic equipment.
Automotive Grade devices are also available which meet
the demanding Automotive Electronics Council's AEC-Q200
qualification requirements
KEMET’s X7R dielectric features a 125°C maximum
operating temperature and is considered temperature
stable. The Electronics Components, Assemblies
and Materials Association (EIA) characterizes X7R
dielectric as a Class II material. Components of this
classification are fixed, ceramic dielectric capacitors
suited for bypass and decoupling applications or for
frequencydiscriminating circuits where Q and stability of
capacitance characteristics are not critical. X7R exhibits
a predictable change in capacitance with respect to time
and voltage, boasting a minimal change in capacitance
with reference to ambient temperature.
For added reliability, KEMET's flexible termination
technology is an available option that provides superior
flex performance over standard termination systems. This
technology was developed to address flex cracks, which are
the primary failure mode of MLCCs and 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
body of the MLCC, therefore mitigating flex cracks which
can result in low IR or short circuit failures.
