161D120

Overview

The Hammond Manufacturing 161D120 is a low voltage power transformer designed for printed circuit board (PCB) mounting. It features a laminated core and concentric wound split bobbin construction. The unit operates at 50Hz or 60Hz with a 1VA rating. Electrical specifications include a 115V primary input. Secondary options provide either parallel 60V at 16mA or series 120V center-tapped at 8mA. It utilizes through-hole termination for secure board integration.

Feature Summary

• Concentric wound split bobbin design for compact PCB integration
• Laminated core construction supporting 50Hz and 60Hz operation
• Through-hole termination style for reliable board mounting

Applications

• Low voltage power supply circuits
• Control panel internal power distribution
• Electronic equipment requiring isolated AC power

Procurement Notes

Verify the specific secondary configuration required, as the part number denotes a standard specification that may offer parallel or series secondary options depending on the exact datasheet revision. Confirm physical dimensions against the target PCB footprint to ensure compatibility with the through-hole mounting style. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a small form factor transformer is needed for PCB applications. Ensure the primary voltage matches the system input of 115V. Choose based on whether the application requires the higher current parallel secondary or the higher voltage series secondary option. Verify that the 1VA power rating meets the load requirements of the downstream circuitry.

Part Context

This component belongs to Hammond Manufacturing's line of electrical enclosure and power transformation products. It serves as a critical interface for stepping down mains voltage to safer levels for sensitive electronics. The product is categorized under power transformers specifically designed for board mount applications rather than chassis or DIN rail mounting.
