Feb 2007 Ver. 12b [LAND PATTERN (TDK Recommended)] 2.60 mm 0.60 mm 0.35 mm 1.95 mm 0.55 mm 0.20 mm 0.65 mm 0.35 mm Fig 3 Note1: Pin 2 of the filter provides a DC feed connection to the balanced ports. In the event that this function is used, Pin 2 should be connected to ground using a 15pF de-coupling capacitor. Note2: In the event that the pin 2 function is not used, the pin should be left unconnected.
