TDK Epcos B722 Metal Oxide Varistor, 15J, 50V AC

The TDK Epcos B722 StandarD series varistor is a high-performance radial-leaded component, engineered from metal oxide for robust over-voltage protection. Designed with a round shape, it offers a wide operating voltage range from 11V RMS to 1100V RMS, making it exceptionally versatile for numerous circuit applications.

These varistors function as control or compensation elements within circuits, serving a dual purpose: they either create optimal operating conditions or shield sensitive components from damaging transient voltage spikes. Their voltage-dependent characteristics provide a reliable, automated response to high-energy surges, clamping the voltage to a safe level almost instantaneously.

Key performance features include a high surge current rating of up to 8kA and a peak energy handling capability from 0.3J to 410J. This specific model offers a peak energy rating of 15J. It is approved to major international safety standards, including UL, CSA, VDE, CQC (S05/07, S10/S14, S20), and IEC, ensuring compliance for global projects.

Built for reliability in demanding environments, the varistor operates across a temperature range of -40°C to 85°C and is rated for 1000 hours of endurance at 85°C. It features a varistor voltage tolerance of ±10% and ±5%, and its construction is UL94V-0 flame retardant with a protective epoxy resin coating.
