## **ChipGuard[®] MLA Series Varistor ESD Clamp Protectors** 

## ~~**Description**~~ 

The ChipGuard[®] CG0402MLA and CG0603MLA Series are 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.
