Features ■ ■ ■ ■ ■ 0402 and 0603 package options Rated for IEC 61000-4-2, level 4 Withstands multiple ESD strikes Low capacitance and leakage currents for invisible load protection Tape and reel packaging Chip Guard® MLD Series Varistor ESD Clamp Protectors Description The Chip Guard® CG0402MLD and CG0603MLD Series has been specifically 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 specifications targeted for high speed data applications. The Chip Guard® MLD Series has been manufactured to provide very low cpacitance with excellent clamp qualities, making the family almost transparent under normal working conditions.
