Chip Guard® ESD Clamp Protection Bourns® family of Chip Guard® electrostatic discharge (ESD) protectors is based on a Multilayer zinc oxide Varistor (MLV) technology. The MLV technology provides excellent electrical performance with a competitive solution for many ESD requirements. The Chip Guard® family is designed to protect sensitive electronic circuits from the threat of ESD to IEC61000-4-2 to level 4 in the ultra-small 0402 and 0603 type packages. is less critical. The MLE series has been designed to provide a tolerance on the capacitance of the ESD protector to allow engineers to...

Product Selection Guide The family of Chip Guard® electrostatic discharge (ESD) protectors are currently limited to a small range of voltage options. However, the MLV process allows a wider range to be manufactured. Should a voltage that is not highlighted in the current selection be required, please inquire with your local representative as the family will be expanding in the future.

ESD and Chip Guard® Technology Electrostatic Discharge occurs when a charge is exchanged between two objects of unequal charge potential. ESD, most often between people and metal objects is a result of a build-up of electrons that behave as a capacitor when dielectric isolation is available. Man-made materials such as the sole of a shoe achieve dielectric isolation, while a person walking on carpet creates kinetic energy. The International Electro-technical Commission (IEC) developed a human model ESD event that allows designers to take adequate protection in their electrostatic...
