Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
ArcShield™ Technology, High Voltage, X7R Dielectric,
500 – 1,000 VDC (Commercial & Automotive Grade)
Overview
KEMET ArcShield high voltage surface mount capacitors
in X7R dielectric are designed for use in high voltage
applications susceptible to surface arcing (arc-over
discharge).
The phenomenon of surface arcing is caused by a high
voltage gradient between the two termination surfaces or
between one of the termination surfaces and the counter
internal electrode structure within the ceramic body. It
occurs most frequently at application voltages that meet
or exceed 300 V, in high humidity environments, and in
chip sizes with minimal bandwidth separation (creepage
distance). This phenomenon can either damage surrounding
components or lead to a breakdown of the dielectric
material, ultimately resulting in a short-circuit condition
(catastrophic failure mode).
Patented ArcShield technology features KEMET's highly
reliable base metal dielectric system combined with a
unique internal shield electrode structure that is designed
to suppress an arc-over event while increasing available
capacitance. Developed on the principle of a partial Faraday
cage, this internal system offers unrivaled performance
and reliability when compared to external surface coating
technologies.
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.
KEMET’s ArcShield high voltage surface mount MLCCs are
available in Automotive Grade, which undergo stricter testing
protocol and inspection criteria. Whether under-hood or
in-cabin, these devices are designed for mission and safety-
critical automotive circuits or applications requiring proven,
reliable performance in harsh environments. Automotive Grade
devices meet the demanding Automotive Electronics Council's
AEC-Q200 qualification requirements.
