Notes
1. For DIP package, replace ‘S’ in model number with ‘D’.
2. Add suffix ‘-H’ to model number for 3000 VDC isolation.
3. Operation at no load will not damage unit but it may not meet all specifications.
4. All dimensions in inches (mm).
5. Pin pitch tolerance: ±0.014 (±0.35)
6. Case tolerance: ±0.02 (±0.5)
7. Weight: SIP 0.003 lbs (1.4 g), DIP 0.004 lbs (1.8 g)
