In SFI’s product lineup, the MLE Series from the MLV Family and the STS Series from the SGD Family are widely used in consumer electronics such as smartphones, tablets, and wearable devices. They play a critical role in providing ESD (electrostatic discharge) protection for components like USB ports, audio/video interfaces, push buttons, and other 3C-related applications.SFI products not only meet the ESD protection needs of the 3C industry but also comply with IEC61000-4-2 Level 4 certification standards, offering stable and efficient voltage protection solutions to leading global 3C product manufacturers.

SFI’s multilayer varistor STD Series from the SGD Family is widely used in high-speed transmission interfaces such as PCIe, Thunderbolt, USB4, HDMI 2.1, and DisplayPort 2.0 to provide ESD protection for high-frequency data processing.ESD can sometimes cause data errors, signal degradation, or even damage to ICs and ports, so appropriate protection design is essential.SFI’s products not only address ESD damage issues in high-speed transmission, but also comply with IEC61000-4-2 Level 4 standards. With ultra-low capacitance, they ensure that data transmission is unaffected, providing stable and efficient voltage protection solutions to leading global manufacturers in high-speed communication industries.
