New Chip Varistors Protect against ESD

Because ICs and semiconductor components of digital electronic devices are vulnerable to damaging electrostatic discharge, ESD protection is necessary. Mobile phones, smartphones and digital audio players are particularly susceptible, as they are in contact with the user whose body itself is a source of static electricity. The importance of ESD protection has also increased as the latest slim and compact devices are sacrificing grounding performance, and increasing the number of input-output interfaces for improved functionality.
