Overview
The Hammond Manufacturing 161G120 is a laminated core power transformer designed for board mount applications. It features a low voltage configuration with a 115V primary winding and dual secondary options: parallel connection providing 60V at 170mA, or series connection providing 120V C.T. at 85mA. The unit has a 10VA rating and utilizes through-hole mounting technology.
Feature Summary
- Laminated core construction for efficient power conversion
- Low voltage PCB mount design for compact integration
- Dual secondary winding capability for flexible voltage output configurations
Applications
- Industrial control panels requiring isolated power supplies
- Electronic equipment needing low voltage AC distribution
- Custom circuit boards requiring specific step-down transformer solutions
Procurement Notes
Verify the specific datasheet version to confirm pinout orientation and mounting hole dimensions before integration. Ensure the selected secondary configuration (parallel or series) matches the target circuit requirements. Confirm compliance with relevant safety standards for the intended deployment environment.
Selection Notes
Select this component when a 10VA isolation transformer is required for low voltage AC applications. Choose between parallel 60V or series 120V outputs based on load current needs. Verify that the PCB layout accommodates the through-hole lead spacing and physical footprint of the laminated core assembly.
Part Context
This part belongs to the Hammond 161 series of power transformers, which are widely used in industrial and commercial electronics. The series offers various VA ratings and voltage combinations, providing standardized solutions for OEMs designing custom power supply stages within larger electronic systems.
Replacement Considerations
Consult official cross-reference lists for equivalent laminated core transformers with matching 10VA ratings and compatible pinouts. Verify that any substitute maintains the same insulation class and thermal performance characteristics.
