Electrical Connections

Case Design

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

(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.
