Overview
The Hammond Manufacturing 161H120 is a laminated core power transformer designed for low voltage PCB mounting applications. It features a single primary winding rated for 115V AC input. The secondary configuration offers a center-tapped output of 120V C.T., providing 200mA in series connection or 400mA in parallel connection. With a total power rating of 24VA, this component utilizes through-hole technology for secure board integration.
Feature Summary
- Laminated core construction for efficient magnetic coupling
- Low voltage design suitable for printed circuit board mounting
- Center-tapped secondary winding configuration
- Through-hole termination for mechanical stability
Applications
- Industrial control panel power supplies
- Electronic equipment requiring isolated low voltage DC conversion
- Automation systems with PCB-mounted power requirements
Procurement Notes
Verify the specific secondary current requirement (200mA series vs 400mA parallel) against the system design before ordering. Confirm that the 115V primary voltage matches the available supply line. Ensure the PCB layout accommodates the through-hole pin spacing and physical dimensions of the laminated core assembly to prevent mechanical interference.
Selection Notes
Select this model when a compact, board-mount solution is required for 24VA isolation. The center-tapped secondary allows for full-wave rectification circuits. Consider thermal management capabilities if operating near the maximum VA rating. Verify that the open construction style meets the environmental protection needs of the final enclosure.
Part Context
This component belongs to the Hammond 160-161 Series of low voltage PC board mount transformers. This series ranges from 0.5 VA to 24 VA ratings. These units are engineered for direct integration into electronic assemblies where space constraints limit the use of larger chassis-mounted alternatives.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
