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-circuit-

boards 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.
