TDK B722 StandarD Metal Oxide Varistor, 420V ac, 90J

The TDK B722 StandarD series are high-performance, round-shaped, radial-leaded Metal Oxide Varistors (MOVs). These components are essential for protecting electronic circuits from damaging transient voltage spikes, thanks to their voltage-dependent characteristics. With a wide operating voltage range from 11V_RMS to 1100V_RMS, they offer versatile application possibilities in various demanding environments.

These varistors function as control or compensation elements, ensuring optimal operating conditions and safeguarding sensitive components against excessive voltage surges. The high surge current rating of up to 8kA and a substantial peak energy handling capacity of 90J make them exceptionally robust for industrial and safety-critical applications. Their construction features a flame-retardant epoxy resin coating, rated UL94V-0, for enhanced safety and durability.
