Vishay’s Industry-First VJ HVArc Guard® Surface-Mount X7R MLCCs Prevent Surface Arc-Over With Voltage Ratings From 250 VDC to 1000 VDC and Capacitance Range of 100 pF to 0.27 µF


New Devices Offer Twice the Voltage Breakdown of Standard Capacitors in Smaller Case Sizes

ishay Intertechnology, Inc. (NYSE: VSH) today announced the release of the industry’s first surface-mount X7R multilayer ceramic chip capacitors (MLCCs) designed to prevent surface arc-over. The new devices provide maximum capacitance in high-voltage ratings and an increased capacitor voltage breakdown.

The new VJ1206, VJ1210, VJ1808, and VJ1812 HVArc Guard® MLCCs feature a unique, patent-pending internal design structure that prevents surface arc-over at high voltages. This design allows for higher capacitances than standard high-voltage MLCCs, 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, the new devices will be used in lighting systems and power supplies for medical, computer, motor control, construction and mining, and telecommunications applications.

The four HVArc Guard capacitors released today feature capacitances ranging from 100 pF to 0.27 µF, and offer twice the standard voltage breakdown with voltage ratings from 250 VDC to 1000 VDC. The devices eliminate the need for conformal coating, and can replace wire-leaded through-hole capacitors.

Samples and production quantities of the new VJ HVArc Guard surface-mount X7R MLCCs are currently available, with lead times of approximately eight weeks.
