161H12

Overview

The Hammond Manufacturing 161H12 is a low voltage power transformer designed for printed circuit board (PCB) mounting. It features a single primary winding rated at 115 VAC and a dual secondary winding configuration providing 12.6 VAC center-tapped output. The unit has a power rating of 24 VA with a secondary current capacity of 2 A. It utilizes solder pin termination for through-hole installation.

Feature Summary

• Designed for direct PCB mounting via through-hole solder pins
• Provides isolated low voltage AC output from standard line voltage
• Features dual secondary windings for center-tapped applications

Applications

• Low voltage power supply circuits
• Control panel transformers
• Electronic equipment requiring isolated AC sources

Procurement Notes

Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct voltage and current ratings. Confirm that the package style matches your PCB footprint requirements. Check for RoHS compliance status in the latest datasheet before procurement.

Selection Notes

Select this component when a compact, board-mount solution is required for stepping down 115 VAC to a lower voltage. Ensure the PCB layout supports the through-hole pin spacing and that the enclosure allows for adequate ventilation given the thermal characteristics of laminated transformers.

Part Context

This component belongs to the 161 series of low voltage power transformers manufactured by Hammond Manufacturing. These units are generally characterized by their laminated core construction and suitability for general-purpose electronic applications where space constraints favor board-level integration over chassis mounting.

Replacement Considerations

Consult Hammond Manufacturing catalogs for alternative part numbers within the 161 series that match specific voltage or current requirements. Verify mechanical dimensions and pin configurations before substituting to ensure compatibility with existing PCB layouts.
