| Features 0402 and 0603 package options Rated for IEC 61000-4-2, for applications requiring up to 18 V DC Withstands multiple ESD strikes Low capacitance and leakage currents for invisible load protection Tape and reel packaging ChipGuard(R) MLE Series Varistor ESD Clamp Protectors Description The ChipGuard(R) CG0402MLE and CG0603MLE Series has been designed to provide high frequency attenuation, thereby providing suppression and filtering in a single device. The MLE family also offers protection to ESD standards such as IEC61000-4-2 for applications requiring up to 18 V DC and is available in the industry standard 0603 and 0402 type leadless surface mount packaging.

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 actual device performance in their specific applications.
