The Chip Guard
®
CG0402MLD and CG0603MLD Series have been specically designed to protect sensitive electronic components from
electrostatic discharge damage. The MLD family has been designed to protect equipment to IEC61000-4-2, level 4 ESD specications
targeted for high speed data applications. The Chip Guard
®
MLD Series has been manufactured to provide very low capacitance with
excellent clamp qualities, making the family almost transparent under normal working conditions.
