TECHNICAL INFORMATION
Notes:
1. All dimensions in inches and (millimeters).
2. Units are encapsulated with a low thermal resistance molding compound which has excellent chemical resis-
tance, wide operating temperature range and good electrical properties under high humidity environments. The
encapsulant and outer shell have UL94V-0 ratings. Lead material is brass with a solder plated surface to allow
ease of solderability.
3. GRID: 0.100 inches, (2.54 mm).
4. Pin Placement Tolerance: +0.015", (+.381 mm).
