VJ Series COG Dielectric

By Vishay/Vitramon 102

VJ Series COG Dielectric

Vishay's VJ series of surface-mount open-mode design (OMD) MLCCs are designed to prevent shorts or low insulation resistance due to board flexure cracks, reducing the risk of field failures and lowering warranty costs. To further reduce the risk, the capacitors are available with polymer terminations, which increase board flex by as much as 50%.

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, and telecommunications applications. The devices offer a wide capacitance range of 10 pF to 4700 pF (with C0G dielectric) and 100 pF to 1.8 µF (with X7R dielectric), with excellent reliability and thermal shock performance.
