ArcShield™ Technology, High Voltage, X7R Dielectric,
500 – 1,000 VDC (Commercial & Automotive Grade)
Overview
The 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.
The KEMET ArcShield high voltage surface mount MLCCs are
available in automotive grade, which undergo stricter testing
protocol and inspection criteria. Whether underhood 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.
