ArcShield capacitor technology from Kemet is used in high-voltage applications susceptible to surface arcing, including commercial and automotive applications that meet or exceed 500 V with exposure to high humidity environments. ArcShield devices inhibit surface arc-over discharge, preventing damage to the capacitor and surrounding components on a printed circuit board. Caused by a high-voltage gradient between termination surfaces, surface arcing can damage components or break down dielectric material, leading to failure mode. ArcShield technology’s internal shield electrode system suppresses arc-over while increasing available capacitance. Suitable applications include switch mode power supplies, high-voltage coupling and dc blocking, lighting ballasts, voltage multiplier circuits, and dc/dc converters. RoHS-compliant capacitors feature voltage ratings of 500, 630, and 1000 V with tin-plated termination finish and a flexible termination option available.

As ground vehicles employ more electronic sensing, control and communication systems, design engineers are increasingly utilizing more commercial off-the-shelf (COTS) modules. Though COTS slashes development time and costs, it’s still difficult for many military users to find COTS boards that meet their low-volume demands for ruggedization and redundancy.
