Malvern, Pa. Vishay Intertechnology, Inc. says it has introduced the industry's first surface-mount C0G multilayer ceramic chip capacitors (MLCCs) designed to prevent surface arc-over at high voltages. The VJ HVArc Guard surface-mount devices provide maximum capacitance at high-voltage ratings with an increased capacitor voltage breakdown.
The VJ0805, VJ1206, and VJ1210 HVArc Guard MLCCs feature a unique and patent-pending internal design structure that prevents surface arc-over at high voltages. This design allows for higher capacitances and facilitates the use of smaller case sizes in high-voltage products, allowing for device miniaturization and lower component cost. These devices are optimized for buck and boost DC-to-DC converters, voltage multipliers for flyback converters, and lighting ballast circuits, and may be used in lighting systems and power supplies for medical, computer, motor control, and telecommunications applications.
The three HVArc Guard capacitors offer a capacitance value range of 10 pF to 2700 pF in smaller case sizes than standard high-voltage MLCCs, and offer twice the standard voltage breakdown with voltage ratings from 1000 Vdc to 1500 Vdc. The devices eliminate the need for conformal coating, and can replace wire leaded through-hole capacitors.
Pricing: Starts at $0.14 each for U.S. delivery.
Availability: Samples and production quantities of the VJ HVArc Guard surface-mount C0G MLCCs are currently available, with lead times of approximately eight weeks.
