3 Description
The TPDxF202 devices are four or six-channel EMI
filters, designed particularly to suppress EMI noise in
the cell phone and other portable applications. These
filters also provide a Transient Voltage Suppressor
(TVS) diode circuit for Electrostatic Discharge (ESD)
protection which prevents damage to the application
when subjected to ESD stress far exceeding IEC
61000-4-2 (Level 4). The pi-style C-R-C filter provides
symmetric filter performance in the data lines to and
from either side of the filter.
Due to the tiny parasitics of the DSBGA package, the
TPDxF202 filters provide excellent signal attenuation
(–40 dB at 1 GHz) at the typical cell-phone carrier
frequency ranges.
The ultra thin (0.3-mm package height, when mounted
on board) space-saving YFU package enables the
TPDxF202 devices to mount on the printed-circuitboards
where height is a key constraint.
The TPDxF202 devices are specified for –40°C to
85°C operation.
A typical application for TPDxF202 devices are in
portable equipment with DVI, VGA, SVGA, SIM Card,
and other data interfaces.
