Which of the following best describes the categorization of ESDS devices by their sensitivity?

The categorization of Electrostatic Discharge Sensitive (ESDS) devices by their sensitivity is best described as Class 1, Class 2, and Class 3. This classification system is widely recognized in the electronics industry and serves to identify the level of sensitivity of different devices to electrostatic discharge.

Class 1 devices are the most sensitive and can be damaged by relatively low levels of electrostatic discharge, meaning they require the highest level of protection during handling and processing. Class 2 devices are moderately sensitive; while they can still be damaged by electrostatic discharge, they can tolerate higher levels than Class 1 devices. Class 3 devices are the least sensitive of the three classes and can withstand the highest levels of electrostatic discharge without sustaining damage.

This classification is crucial for ensuring proper handling procedures are followed, preventing damage and ensuring reliability in electronic systems, especially in avionics where component integrity is vital. The other options, while they represent different categorization systems, do not correspond to the established classifications of ESDS sensitivity in industry standards.
