Varistors Protect Mobile Devices Against ESD

The new EIA 0201 multilayer chip varistors from Taiyo Yuden are designed to protect slim and compact handheld mobile devices against electrostatic discharge (ESD). Both the VR063 101A120 and the VR063 101A080 varistors feature the same voltage, ESD resistance and other electrical characteristics as the company's previous EIA 0402 model. However, they measure only 0.6 x 0.3 x 0.3mm and are 78 per cent smaller than the EIA 0402.

As ICs and semiconductor components of digital electronic devices are vulnerable to damaging ESD, protection is necessary. Mobile phones, smartphones and digital audio players are particularly susceptible as they are in contact with the user, whose body 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 USD0.05 (GBP0.03) per unit.
