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
The TPDxF202 devices are specified for 40°C to 85\xC2deg;C operation.
A typical application for TPDxF202 devices are in portable equipment with DVI, VGA, SVGA,
SIM Card, and other data interfaces.
