NOTES: All dimensions are in inches (mil-
limeters).
GRID: 0.100 inches (2.54 millimeters)
Pin Placement Tolerance: ±0.015
Marked with: specic model ordered, date
code, job code.
MATERIAL: Units are encapsulated in a low
thermal resistance molding compound which
has excellent chemical resistance, wide oper-
ating temperature range, and good electrical
properties under high humidity environments.
The encapsulant and outer shell of the unit
have UL94V-0 ratings. Lead base metal is
half hard brass; lead nish is 100-300 micro-
inches matte tin over a barrier layer of 5-40
micro-inches of nickel.
