Additional Details:

The V18MLA1210NT has a maximum allowable AC voltage of 18V. It is designed to limit transient voltages to a specific clamping voltage, diverting the surge current away from protected components. The operating temperature range is typically -40°C to +85°C. This varistor is surface mounted using reflow soldering techniques. Refer to the Littelfuse datasheet for comprehensive specifications, including surge current ratings for various waveforms (e.g., 8/20µs) and application guidelines. The construction utilizes a metal oxide ceramic material, providing the necessary non-linear resistance characteristics for effective transient voltage suppression.
