Environmental Characteristics
The Chip Guard
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.

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.
