Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
High Voltage with Flexible Termination System (HV FT-CAP)
X7R Dielectric, 500 – 3,000 VDC (Commercial & Automotive Grade)
Overview
KEMET’s High Voltage with Flexible Termination (HV FT-CAP)
surface mount MLCCs in X7R dielectric 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. Featuring several of the highest
CV (capacitance/voltage) values available in the industry, these
devices utilize a pliable and conductive silver epoxy between the
base metal and nickel barrier layers of the termination system.
The addition of this epoxy layer 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
flexible termination 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.
Combined with the stability of an X7R dielectric and designed to
accommodate all capacitance requirements, these flex-robust
devices are RoHS Compliant, offer up to 5 mm of flex-bend
capability and exhibits a predictable change in capacitance with
respect to time and voltage. Capacitance change with reference to
ambient temperature is limited to ±15% from -55°C to +125°C.
Automotive Grade is available for applications requiring proven,
reliable performance in harsh environments. Whether under-hood
or in-cabin, these capacitors are designed for mission and safety
critical automotive circuits. Stricter testing protocol and inspection
criteria have been established for automotive grade products in
recognition of potentially harsh environmental conditions. KEMET
automotive grade series capacitors meet the demanding Automotive
Electronics Council's AEC–Q200 qualification requirements.
The HV FT-CAP offers low leakage current, exhibits low ESR at
high frequencies and finds conventional use as snubbers or filters
in applications such as switching power supplies and lighting
ballasts. Their exceptional performance at high frequencies has
made them a preferred choice of design engineers worldwide.
In addition to their use in power supplies, these capacitors
are widely used in industries related to automotive(hybrid),
telecommunications, medical, military, aerospace, semiconductors
and test/diagnostic equipment.
