1. These package dimensions are within allowable dimensions of
JEDEC MO-153-ADT, Issue F.
2. Dimensioning and tolerancing per ANSI Y14.5M-1982.
3. Dimension 鈥淒鈥?does not include mold flash, protrusions or gate
burrs. Mold flash, protrusion and gate burrs shall not exceed
0.15mm (0.006 inch) per side.
4. Dimension 鈥淓1鈥?does not include interlead flash or protrusions.
Interlead flash and protrusions shall not exceed 0.15mm (0.006
inch) per side.
5. The chamfer on the body is optional. If it is not present, a visual
index feature must be located within the crosshatched area.
6. 鈥淟鈥?is the length of terminal for soldering to a substrate.
7. 鈥淣鈥?is the number of terminal positions.
8. Terminal numbers are shown for reference only.
9. Dimension 鈥渂鈥?does not include dambar protrusion. Allowable
dambar protrusion shall be 0.08mm (0.003 inch) total in excess
of 鈥渂鈥?dimension at maximum material condition. Minimum space
between protrusion and adjacent lead is 0.07mm (0.0027 inch).
10. Controlling dimension: MILLIMETER. Converted inch dimen-
sions are not necessarily exact. (Angles in degrees)
11. Dimensions 鈥淧鈥?and 鈥淧1鈥?are thermal and/or electrical enhanced
variations. Values shown are maximum size of exposed pad
within lead count and body size.
