Multilayer Chip Varistors Protect Hand-Held Mobile Devices Against Electrostatic Discharge

Mon, 03/22/2010 - 10:45am

Multilayer Chip VaristorNew EIA 0201 Multilayer Chip Varistors from Taiyo Yuden are designed to protect today’s slim and compact hand-held mobile devices against electrostatic discharge (ESD). Both the VR063 101A120 and the VR063 101A080 boast the same varistor voltage, ESD resistance and other electrical characteristics as Taiyo Yuden’s previous highly regarded EIA 0402 model. However, they measure only 0.6 x 0.3 x 0.3 mm, and are 78% smaller than the EIA 0402.

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.

The VR063 101A120 and the VR063 101A080 Multilayer Chip Varistors are currently being produced in volume quantities. The sample price is $0.05/unit.
