NOTES:

1.

Dimensions are in inches.

2.

Metric equivalents are given for general information only.

3.

Dimension "A" controls the overall package thickness. When a window lid is used, dimension "A" must

increase by a minimum of .010 inch (0.254 mm) and a maximum of .040 inch (1.020 mm).

4.

The corner shape (square, notch, radius, etc.) may vary at the manufacturer's option, from that shown on

the drawing.

5.

Dimensions "B3" minimum and "L3" minimum and the appropriately castellation length define an

unobstructed three-dimensional space traversing all of the ceramic layers in which a castellation was

designed. (Castellations are required on bottom two layers, optional on top ceramic layer.) Dimension

"B3" maximum and "L3" maximum define the maximum width and depth of the castellation at any point on

its surface. Measurement of these dimensions may be made prior to solder dipping.

6.

Lead 4 = no connection.
