EMI Filter 70dB Flat Style SMD T/R

The TPDxF202 are four, six-channel EMI filters, designed particularly to suppress EMI noise in the cell phone and other portable applications. These low-pass filters also protect internal core citcuity against system level ESD strikes at the external interface pins. The pi-style C-R-C filter provides symmetric filter performance in the data lines to/ from either side of the filter. Due to tiny package parasitics of the WCSP package, the TPDxF202 series of filters provide excellent signal attenuation (–40dB at 1GHz) 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 the height is a key constraint. The TPDxF202 devices offer very robust system level ESD protection specifications at both input and output ports,which eliminates the need for any additional ESD clamp diodes at the external interface pins. The TPDxF202 devices are specified for –40°C to 85°C operation.
