Which ESDS class is categorized as "extremely sensitive"?

The correct categorization for "extremely sensitive" components falls under Class 1 within the Electronic Sensitive Device (ESD) classifications. Class 1 devices are defined by their heightened vulnerability to electrostatic discharge, necessitating stringent handling protocols to prevent damage.

Class 1 devices can be easily affected by even minor electrostatic discharges, which can cause catastrophic failures or permanent damage. The handling of these components requires the strictest adherence to ESD protective measures such as the use of grounding equipment, antistatic wrist straps, and controlled environments.

Understanding the implications of the various classes helps in identifying the appropriate ESD control measures and ensures the reliability of electronic systems, particularly in avionics where component failure can have critical consequences. As a result, anyone working with ESDS must be well-versed in the sensitivity levels and required precautions for each class.
