Procurement Notes
Verify the specific manufacturer part number against official Hammond Manufacturing documentation to ensure compatibility with your design requirements. Confirm that the 115V primary input matches your source voltage and that the 0.5 VA rating meets your load demands. Cross-reference datasheet specifications for thermal performance and insulation ratings before finalizing component selection.
Selection Notes
Select this component when a compact, board-mount solution is required for stepping down mains voltage to low levels. Ensure the physical dimensions fit the available PCB real estate and that the lead spacing accommodates the target layout. Consider the thermal environment, as the operating limit reaches +130°C, which may influence nearby component placement.
Part Context
This transformer belongs to the 161 series of low voltage PCB mount units from Hammond Manufacturing. These components are engineered for general-purpose power conversion tasks where space efficiency and reliable electrical isolation are priorities. The series offers various voltage and wattage combinations to suit diverse electronic design needs.
Replacement Considerations
Consult official Hammond Manufacturing substitution guides or equivalent distributor cross-reference lists for verified alternative part numbers. Ensure any replacement maintains identical electrical parameters, including 115V primary, 10V CT secondary, and 0.5 VA rating.
