适用于 LCD 显示屏且具有 ESD 保护功能的四通道 EMI 滤波器

 

描述

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\xC2deg;C operation.

A typical application for TPDxF202 devices are in portable equipment with DVI, VGA, SVGA, SIM Card, and other data interfaces.
