TDK Epcos B722 Metal Oxide Varistor 25V ac 26.0J

The TDK Epcos B722 Series metal oxide varistors are round-shaped, radial-leaded SIOV components designed for exceptional circuit protection and control. Operating across a wide voltage range, these varistors act as control or compensation elements to ensure optimal operating conditions or to safeguard against excessive transient voltages. Their voltage-dependent characteristics make them highly effective at protecting sensitive circuitry from high transient voltage spikes.

This specific varistor offers a voltage rating of 25V AC (31V DC) with a maximum clamping voltage of 77V. It provides robust protection with a peak surge current rating of up to 2kA (at 8/20µs) and a peak energy capacity of 22J (at 10/1000µs). The component is built to last, featuring an endurance of 1000 hours at 85°C, and operates reliably in temperatures ranging from -40°C to 85°C.

Key Features

• High surge current ratings up to 8kA across the series
• UL94V-0 rated flame retardant and epoxy resin coated
• Approved by UL, CSA, VDE, CQC, and IEC
• Varistor voltage tolerance of ±10% and ±5%

Ideal for demanding environments, this radial-leaded MOV is perfectly suited for industrial and safety applications where reliable voltage suppression is critical.
