Epcos TDK B722 StandarD Varistor, 4.2J 50V ac

The Epcos B722 StandarD series varistor is a round, radial-leaded SIOV (metal oxide varistor) component, designed for reliable circuit protection and voltage regulation. Its wide operating voltage range from 11 VRMS to 1100 VRMS makes it highly versatile for diverse electronic applications.

As a control or compensation element, this varistor ensures optimal operating conditions within a circuit, safeguarding sensitive components against damaging transient voltage spikes. Its voltage-dependent characteristics allow it to respond rapidly to overvoltage events, effectively clamping excessive voltage and protecting downstream equipment. The component boasts high surge current ratings and is designed to handle peak energy dissipation, providing a robust defence against electrical surges.

Manufactured to exacting standards, it features a flame-retardant epoxy resin coating rated UL94V-0, enhancing safety in the event of fault conditions. It is approved by major international safety bodies, ensuring compliance and reliability for professional and industrial use. The varistor operates reliably across a broad temperature range, offering consistent performance in demanding environments.

With its proven endurance and precise voltage tolerance, the Epcos B722 varistor is a fundamental component for enhancing the longevity and stability of electronic systems, from industrial controls to safety-critical circuits.
