Vishay VJ HVArc Guard SMT MLCCs
Vishay Vitramon VJ HVArc Guard Surface Mount (SMT) Multilayer Ceramic Chip Capacitors (MLCCs) features efficient reliability and high-voltage performance, as well as higher capacitance and smaller case size, saving board space compared to standard high-voltage MLCCs. The VJ HVArc Guard MLCCs are available in C0G (NP0) dielectric variant and X7R dielectric variant. These MLCCs come with a reliable Noble Metal Electrode (NME) system and protect against surface arc over. The VJ HVArc Guard SMT MLCCs can operate in the temperature range of -55°C to +125°C with an insulating resistance of 100ΩF at +125°C. Vishay Vitramon VJ HVArc Guard SMT MLCCs are optimized for applications involving buck and boost dc-to-dc converters, voltage multipliers for flyback converters, lighting ballast circuits, and telecommunications.
