TDK B722 Series Metal Oxide Varistor (MOV), 460V ac, 100J

The TDK B722 Series Standard varistors are round, radial-leaded SIOV metal oxide varistors (MOVs) designed for reliable circuit protection. These components feature a wide operating voltage range, making them suitable for diverse electronic applications where safeguarding against voltage transients is critical. Their voltage-dependent characteristics allow them to act as a dynamic barrier, clamping excessive transient voltage spikes and preventing damage to sensitive downstream components.

Constructed with a robust epoxy resin coating and rated UL94V-0 for flame retardancy, these varistors offer enhanced safety and durability. They are approved to major international standards, including UL, CSA, VDE, CQC, and IEC, ensuring compliance for use in industrial and safety-critical equipment. The component is engineered for long-term reliability, capable of enduring 1000 hours at 85°C.

With a high surge current rating and substantial energy absorption capability, this varistor is an essential element for robust circuit design. Its precise voltage tolerance ensures consistent performance, providing optimal operating conditions or protection in your circuits.
