One world. One KEMET

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.
