The product is HVArc Guard® C0G (NP0) series produced by Vishay Vitramon, using surface-mount, precious metal technology, wet build process MLCC that protect against surface arc-over. The series products have high capacitance, small case size, voltage breakdown voltage is twice that of some competitor products, excellent reliability, high voltage performance and so on. It can be used in DC-to-DC converters, power converters, flyback converters, lighting ballast circuits and other circuits.
The VJ HVArc Guard C0G (NPO) is a surface‑mount multilayer ceramic capacitor designed to prevent surface arc‑over in high‑voltage applications. It offers higher capacitance in smaller case sizes and twice the voltage breakdown of comparable parts, with optional polymer termination for flex‑crack resistance.
