ChipGuard® MLA Series Varistor ESD Clamp Protectors
Description
The ChipGuard® CG0402MLA and CG0603MLA Series is based on a multilayer metal oxide technology. The MLA family is designed to
protect sensitive electronic circuits from the threat of electrostatic discharge ESD. The MLA series is available from 5.5 V to 26 V DC working
voltages.
The wide operating voltage and temperature range makes this family ideally suited to IC power supplies, signal and control line protection.

This product can be damaged by rapid heating, cooling or localized heating.
Heat shocks should be avoided. Preheating and gradual cooling recommended.
Excessive solder can damage the device. Print solder thickness of 150 to 200 um recommended.
Solder gun tip temperature should be kept below 280 °C and should not touch the device directly. Contact should be less than 3 seconds. A solder gun under
30 watts is recommended.
Specifications are subject to change without notice.
Customers should verify device performance in their specific applications.
