Figure 9-3 QFN-16 Package Dimensions
The FT121Q is supplied in a RoHS compliant leadless QFN-16 package. The package is lead ( Pb ) free,
and uses a ‘green’ compound. The package is fully compliant with European Union directive 2002/95/EC.
This package is nominally 3mm x 3mm. The solder pads are on a 0.50mm pitch. The above mechanical
drawing shows the QFN-16 package. All dimensions are in millimetres.
The centre pad on the base of the FT121Q is internally connected to GND pin, and can be left
unconnected, or connected to ground (recommended).
