TDK Epcos B722 StandarD Varistor, 33J, 60V AC

The TDK Epcos B722 StandarD series comprises robust, round, radial leaded SIOV metal oxide varistors (MOVs). These components feature a wide operating voltage range from 11V_RMS to 1100V_RMS, making them highly versatile for numerous circuit protection and conditioning applications. Their voltage-dependent characteristics allow them to act as highly effective barriers against excessive transient voltage spikes, safeguarding sensitive electronics by clamping dangerous over-voltages.

Certified to major international safety standards including UL, CSA, VDE, CQC (S05/07, S10/S14, S20), and IEC, these varistors are designed for reliable performance in demanding environments. They offer high surge current ratings up to 8kA and a broad peak energy handling capability from 0.3J to 410J, with this specific model rated for 33J. The epoxy resin coating and UL94V-0 flame-retardant rating ensure both durability and safety, preventing the spread of flame.

Built to endure harsh conditions, the B722 series operates across a temperature range of -40°C to +85°C and is tested for 1000 hours of endurance at 85°C. Available with a varistor voltage tolerance of ±10% or ±5%, they provide precision and reliability for critical circuit designs. Their primary function is to serve as control or compensation elements, either to establish optimal operating conditions or to provide robust protection against damaging voltage transients in industrial and safety-critical equipment.
