TDK B722 Varistor, 65J, 250V AC Radial Leaded

The TDK B722 Standard Series is a round-shaped, radial-leaded metal oxide varistor (MOV) designed to protect circuits from excessive transient voltages and to serve as a control or compensation element. With a wide operating voltage range from 11V RMS to 1100V RMS, this varistor is suitable for a variety of applications. The voltage-dependent characteristics enable it to clamp high transient voltage spikes, ensuring the safety and reliability of your electronic equipment.

This varistor offers a high surge current rating of up to 8kA (with a 4.5kA peak surge current at 8/20µs for this specific model) and a peak energy rating of 65J (10/1000µs), providing robust protection against power surges. The component is approved by UL, CSA, VDE, CQC, and IEC, meeting stringent safety standards. It operates within a temperature range of -40°C to 85°C and features an endurance of 1000 hours at 85°C.

The varistor has a ±10% and ±5% voltage tolerance, and its epoxy resin coating is rated UL94V-0 for flame retardancy, ensuring dependable performance even in demanding conditions. The package dimensions are 43mm in height, 33mm in width, and 15mm in depth, with a weight of 4 grams.
