Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
ArcShield Technology, High Voltage, X7R Dielectric,
500VDC-1000VDC (Commercial & Automotive Grade)
Overview
KEMET ”ArcShield” high voltage surface mount capacitors in
X7R Dielectric prevent surface arc-over discharge in high voltage
applications.
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 500V, 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).
“ArcShield” Technology (Patent Pending) features a robust
and unique internal shield electrode system that prohibits arc-
over while increasing available capacitance. This system offers
unrivaled performance and reliability when compared to external
surface coating technologies. Developed on the principle of a
partial Faraday cage, these devices prevent the arc from forming
and significantly reduce resulting failures.
These high voltage devices are available with KEMET's Flexible
termination technology which 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. When
combined with flexible termination technology these devices offer
the ultimate level of protection against a low IR or short circuit
condition.
KEMET’s “ArcShield” high voltage surface mount MLCCs are
manufactured in state of the art ISO/TS 16949:2002 certified
facilities and are available in both commercial and automotive
grades. Automotive grade devices meet the demanding
Automotive Electronics Council's AEC-Q200 qualification
requirements. These devices exhibit a predictable change in
capacitance with respect to time and boast a minimal change in
capacitance with reference to ambient temperature. Capacitance
change is limited to ±15% from -55°C to +125°C.

Parameters/Characteristics
Regarding Aging Rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1000 Hours.
To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Capacitance and Dissipation Factor (DF) measured under the following conditions:
1kHz ± 50Hz and 1.0 ± 0.2 Vrms if capacitance ≤10µF
120Hz ± 10Hz and 0.5 ± 0.1 Vrms if capacitance >10µF
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 & Agilent E4980 have a feature known as Automatic
Level Control (ALC). The ALC feature should be switched to "ON".
