Notes
- Replace ‘S’ in model number with ‘D’ for DIP package. 2. SIP 48 Vin models, dimension is 0.28 (7.20) max. 3. DIP 48 Vin models, dimension is 0.27 (6.88) max. 4. Outputs power-trade. 5. All dimensions in inches (mm). 6. For 48 V models a 10 µF capacitor is required between +Vin and -Vin pins. 7. Operation at no load will not damage unit but it may not meet all specifications. 8. IB Series has no 0V pin. Use -Vout and +Vout pins for output.
