Surface-mount X7R multilayer ceramic chip capacitors (MLCCs) manufactured by Vishay and available from TTI, Inc., the world’s leading authorized specialist distributor of passive, connector and electromechanical components, claim an industry first with a unique patent-pending internal design structure that prevents surface arc over at high voltages. Called HVArc Guard and designated VJ1206, VJ1210, VJ1808 and VJ1812, the MLCCs also deliver maximum capacitance in high-voltage ratings and increased capacitor voltage breakdown.

The HVArc Guard internal structure inherently enables higher capacitances to be manufactured when compared to standard high-voltage MLCCs. It also facilitates the use of smaller case sizes in high voltage devices, enabling end-device miniaturization and reduced component cost.

HVArc Guard MLCCs are optimized for use in buck and boost dc-to-dc converters, voltage multipliers for flyback converters, and lighting ballast circuits. Consequently these surface-mount X7R devices are ideal for use in lighting systems and power supplies for medical, computer, motor control, construction and mining, and telecommunications applications.
