1. All dimensions are in millimetres. Dimensioning and tolerancing schemes are conform to ASME Y14.5M-2018 except

European .

2. Values in inches are converted from mm and rounded to 4 decimal digits.

3. UFQFPN stands for Ultra thin Fine pitch Quad Flat Package No lead: A ≤ 0.60mm / Fine pitch e ≤ 1.00mm.

4. The profile height, A, is the distance from the seating plane to the highest point on the package. It is measured

perpendicular to the seating plane.

5. A1 is the vertical distance from the bottom surface of the plastic body to the nearest metallized package feature.

6. A3 is the distance from the seating plane to the upper surface of the terminals.

7. Dimension b applies to metallized terminal. If the terminal has the optional radius on the other end of the terminal, the

dimension b must not be measured in that radius area.

8. Dimensions D and E do not include mold protrusion, not to exceed 0,15mm.

9. BSC stands for BASIC dimensions. It corresponds to the nominal value and has no tolerance. For tolerances refer to

Table 90

10. N represents the total number of terminals.
