Overview
The Hammond Manufacturing 161FA12-BULK is a low voltage power transformer designed for 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 1.2 VA with a secondary current capacity of 100 mA. It utilizes solder pin termination for through-hole installation and operates at a frequency of 60 Hz.
Feature Summary
- Provides isolated low voltage AC power conversion from standard line voltage
- Features dual secondary windings enabling center-tapped rectifier applications
- Designed for direct surface or through-hole integration onto printed circuit boards
Applications
- Low power electronic control circuits
- Rectifier power supply stages
- Signal isolation interfaces
Procurement Notes
Verify the specific suffix designation against official documentation to confirm packaging format, as bulk designations may indicate loose component handling rather than tape-and-reel delivery. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm that the 1.2 VA rating aligns with the thermal requirements of the target application environment.
Selection Notes
Select this component when a compact, board-mount solution is required for low-power AC-to-AC transformation. The 115V primary input suits North American and similar regional electrical standards. Consider the physical footprint and lead length constraints relative to the PCB layout. Verify that the 100mA secondary current capability meets the load demands of the downstream circuitry without exceeding thermal limits.
Part Context
This model belongs to the 161 series of low voltage transformers manufactured by Hammond Manufacturing. These components are engineered for general-purpose industrial and commercial electronics where space-constrained power conversion is necessary. The series offers various voltage and wattage combinations tailored for different circuit architectures.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other Hammond 161 series variants or consult manufacturer engineering support for equivalent specifications.
