JVA – Zinc Oxide Varistors (discontinued)
The JVA Zinc Oxide Varistor series by jb Capacitors is discontinued, but previously offered robust overvoltage protection with a wide voltage and energy ratio, high clamping voltage performance, and low leakage current.
Designed with a round leaded structure, the JVA series was ideal for high-performance surge suppression, delivering reliable operation with low standby power and no follow-on current.
