| Terminology | Reference Symbol | Description |
|---|---|---|
| Nominal dimensions | - | Mount pad in-line interval |
| Package length | D | Largest dimension of the package length excluding terminals |
| Package width | E | Largest dimension of the package width excluding terminals |
| Seated height | A | Height from the seating plane to the highest point of the package ( including package warp ) |
| 1st standoff height | A1 | Distance from the seating plane to the base plane |
| Package height | A2 | Package height ( including package warp ) |
| Terminal pitch | e | Terminal pitch. This represents theoretical reference dimension. |
| Terminal in-line interval | e1 | Distance between the rows of terminals |
| Terminal width | b or bp | Width of terminal inserted in attachment hole of printed wiring board |
| Maximum terminal width 1 | b1 | Maximum terminal width except for outermost terminal |
| Maximum terminal width 2 | b2 | Maximum width of outermost terminal |
| Terminal thickness | c | Thickness of terminal with plating |
| Terminal length | L | Length from seating plane to terminal tip |
| Tolerance value of terminal center position |  |
Positional tolerance for center axis of the terminal on seating plane. Using the maximum material principle, show the tolerance for maximum terminal width. When terminal width is narrow, allowable tolerance is increased by the difference with the maximum width. |
| Terminal angle | θ | Angle between terminal and surface perpendicular to the seating plane |
| Overhang | Z | Distance between the center of terminal located at the extreme edge and the package edge. |
