Output voltage are -5V,-12V. They are packaged in a compact, overmolded package rated at 1A, 0.5A. Optional lead forming provides a vertical mount product for minimal footprint or a surface mount option for a very low profile. The output is closely regulated and the efficiency is typically 88% at 1A, -5V output at full load. Part Selection Output Voltage Input Voltage Max. Output Current Max. Output Power Typical Efficiency Part Number Surface Mount Part Number Vertical Mount -5V 3.0V – 5.5V 1A 5W 88% S7AH-01F50N V7AH-01F50N -12V 3.0V – 5.5V 0.5A 6W 88% S7AH-01FX2N V7AH-01FX2N Note: Add “0” suffix at the end of the model number to indicate “Tube Packaging”, and “R” for “Reel Packaging”, and “G” for “Tray Packaging”.
