TDK (Epcos) StandarD Metal Oxide Varistor, 2.0J 30V ac

The TDK (Epcos) B722 StandarD series are round, radial-leaded metal oxide varistors (MOVs), designed for reliable circuit protection. These components feature a wide operating voltage range and are engineered to safeguard electronic circuits from damaging transient voltage spikes. Their voltage-dependent characteristics allow them to act as a variable resistor, providing optimal operating conditions or robust protection against excessive voltage surges.

With high surge current ratings and a substantial peak energy handling capability, this specific 2.0J model is built for demanding applications. The component is epoxy resin coated and meets the UL94V-0 flame retardant standard, ensuring both safety and durability in challenging environments. It is approved by major international safety bodies, including UL, CSA, VDE, CQC, and IEC, guaranteeing compliance for use in a wide array of commercial and industrial equipment.

Key Features & Applications

• Robust Protection: Acts as a control or compensation element to protect against high transient voltage spikes, with a clamping voltage (Vc max) of 93V.
• High Reliability: Offers an endurance rating of 1000 hours at 85°C and operates reliably across a temperature range from -40°C to 85°C.
• Precision Tolerances: Available with varistor voltage tolerances of ±10% or ±5%, allowing for precise circuit design.
• Industrial & Safety Use: Ideal for industrial control systems, power supplies, safety-critical circuits, and consumer electronics where surge protection is paramount.
• Compact Design: The 7mm disc case style and radial leads make it suitable for PCB mounting in space-constrained designs.

This varistor is a critical component for enhancing the longevity and reliability of electronic systems, providing a first line of defence against voltage transients that can cause component failure.
