SMD 3220 Large-Format Varistor | High Energy Surge Absorption for Chargers and Energy Storage Systems
The SMD 3220 Series Metal Oxide Varistors are large-format surface-mount surge protection devices designed for high-current, high-energy industrial power circuits. Featuring outstanding energy absorption (tens of joules) and high surge current endurance, they are ideal for new energy systems, power converters, grid busbars, and EV fast-charging modules. With a typical package size of 8.0 × 5.0 mm, the series supports automated SMT assembly and lead-free reflow soldering.
SMD 3220 Series is suitable for high-energy surge protection in:
