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).
“ArcShield” Technology (Patent Pending) 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.

Parameters/Characteristics
Regarding aging rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 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:
1 kHz ±50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 µF
120 Hz ±10 Hz and 0.5 ±0.1 Vrms if capacitance > 10 µF
Note: When measuring capacitance, it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known as
Automatic Level Control (ALC). The ALC feature should be switched to "ON."
