TDK Epcos B722 varistor, 23J energy rating for 300V AC circuits. Certified for industrial surge protection with 8kA surge current.
The TDK Epcos B722 Standard series is a range of high-quality, round-shaped radial leaded SIOV metal oxide varistors (MOVs). These robust components are designed for circuit protection, offering a wide operating voltage range from 11VRMS to 1100VRMS. They function as control or compensation elements, ensuring optimal operating conditions and safeguarding sensitive electronic equipment from damaging transient voltage spikes.
The voltage-dependent characteristics of these varistors make them exceptionally effective at clamping excessive voltage surges. With high surge current ratings up to 8 kA and a broad peak energy range from 0.3J to 410J, they provide reliable protection in demanding environments. This particular model offers a substantial peak energy rating of 23 joules and is approved to major international safety standards, including UL, CSA, VDE, CQC, and IEC.
