SMD Zinc Oxide Varistor DATASHEET: SV1210N470G0A_v209.1.pdf
Description:
The SMD Zinc Oxide Varistor SV1210N470G0A is based on Multilayer fabrication technology. These components are designed to suppress a variety of transient events, including those specified in IEC 61000-4-2 or other standards used for Electromagnetic Compliance (EMC). The SV1210N470G0A is typically applied to protect integrated circuits and other components at the circuit board level. It can operate over a wider temperature range than zener diodes.

Soldering Recommendations:
- Preheat
- The temperature rising speed is suggested to be 2~4 ℃ /s
- Appropriate preheat time will be from 60 to 120 seconds.
- Heating
- Careful about sudden rise in temperture as it may worser the solder ability.
- Set the peal temperature in the range from 215 ℃ to 225 ℃.
- Cooling
- Careful about slow cooling as it may cause the position shift of component.
