VJ HVArc Guard® Surface-Mount MLCCs

 

Vishay and Digi-Key offer prevention of surface arc-over at high voltages


VJ HVArc Guard® Surface-Mount MLCCsHVArc Guard® MLCCs are the industry’s first such devices designed to prevent surface arc-over. Their internal design structure additionally allows for higher capacitances and facilitates the use of smaller case sizes in high-voltage products, allowing for device miniaturization and reducing component cost.

Optimized for applications including buck and boost dc-to-dc converters, voltage multipliers for flyback converters, and lighting ballast circuits, HVArc Guard® MLCCs are ideal for lighting systems and power supplies for medical, computer, motor control, and telecommunications applications.
