Case Design

(The optimum value of this dimension is

dependent on the PCB assembly process

employed.)

All pads consist of 30 microinches (min) electroless gold on 50 micro-

inches (min) electroless nickel over base metal. The metallic center pad

was designed for mechanical support. Grounding of this pad is optional.

Lid symbolization, including terminal 1 locator dot, are in contrasting ink.

Symbolization varies by model number. For purposes of illustration, only

terminal 1 dot is shown.
