Introduction to Surge Immunity Testing and Its Importance<\/strong><\/h2>\n

Surge immunity testing is a critical evaluation process in electrical and electronic product development, ensuring devices can withstand transient voltage disturbances caused by lightning strikes, power grid switching, or electrostatic discharge.
