SMD 1210 High-Energy Varistor | Surge Protection for Power & Automotive Control Lines
The SMD 1210 Series Metal Oxide Varistors are surface-mount overvoltage protection devices designed for medium to high energy surge absorption. Compared to 1206, the 1210 package offers greater current endurance and wider voltage ranges, making it suitable for industrial control, power buses, and automotive ECUs. With fast response (<1ns), low leakage, excellent stability, and full compatibility with reflow soldering,Package size: 3.2 × 2.5 mm.
SMD 1210 Series is widely used in surge/transient protection for:
