ESD and EMI Filtering Solution

The demand for greater integration and more
functionality in consumer electronics, such as cell phones
and other hand−held products, has caused an increase in the
number of data lines being used. These data lines could be
from a PDA’s CPU to the display, or a cell phone’s connector
to the rest of the phone. Because of the size constraints on
many of these products, it is advantageous to have as many
components as possible integrated into a single component.
When large numbers of data lines are required, integration
can reduce part count significantly. For Electrostatic
Discharge (ESD) and Electromagnetic Interference (EMI),
filtering the NUF9001FC offers the capability to provide
protection to ten data lines in a single flip−chip package. By
integrating ESD and EMI protection into a single flip−chip
component, the number of discrete components is reduced
by at least twenty. The size advantage of the NUF9001FC
with its ten lines, enables it to be used across many
platforms. The same part can be used to provide ESD
protection and EMI filtering whether or not all ten lines are used.
