TDK Epcos B722 Metal Oxide Varistor, 510V ac, 190J

The TDK Epcos B722 StandarD Series metal oxide varistors are round-shaped, radial-leaded components designed to provide reliable circuit protection. These voltage-dependent varistors act as control or compensation elements, ensuring optimal operating conditions or safeguarding sensitive circuitry against excessive transient voltage spikes.

Featuring a robust design, they offer high surge current ratings up to 8kA and a peak energy range from 0.3J to 410J. With a wide operating voltage range from 11VRMS to 1100VRMS, they are versatile enough for various industrial and safety applications. The components are UL94V-0 rated flame retardant and feature an epoxy resin coating for enhanced durability.
