TDK EPCOS Metal Oxide Varistor, B722 Series, 150V AC, 4.9J

The TDK EPCOS B722 StandarD series are round-shaped, radial leaded metal oxide varistors (MOVs), engineered to provide robust protection against transient voltage spikes in a wide range of circuits. Their voltage-dependent characteristics make them ideal as control or compensation elements, ensuring optimal operating conditions and safeguarding sensitive components from excessive voltage surges. With a high surge current rating of up to 8kA and a peak energy handling capacity ranging from 0.3J to 410J, these components are built for demanding industrial and safety applications where reliability is critical.

Constructed with a flame-retardant epoxy resin coating and rated UL94V-0, the varistors offer excellent safety and durability. They are approved to major international standards including UL, CSA, VDE, CQC (S05/07, S10/S14, S20), and IEC, providing assurance of quality and compliance for global markets. The component operates reliably across an extensive temperature range from -40°C to +85°C and is tested for an endurance of 1000 hours at 85°C, demonstrating long-term stability.
