Overview
The Hammond Manufacturing 160F28-BULK is a low voltage power transformer designed for printed circuit board (PCB) mounting. It features a single primary winding rated for 115/230V AC input and a dual secondary winding configuration providing 28V center-tapped output. The unit has a power rating of 4.4VA with a secondary current capacity of 160mA. This component utilizes through-hole technology for secure attachment to electronic assemblies.
Feature Summary
- Dual secondary winding design enables center-tapped output configurations
- Through-hole PCB mounting style ensures stable mechanical integration
- Single primary winding supports standard 115/230V AC line voltages
Applications
- Low voltage power supply circuits
- Electronic equipment requiring isolated DC conversion
- Industrial control panel instrumentation
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm bulk packaging status and exact electrical tolerances. Ensure that the 160F28-BULK part number matches the required 4.4VA rating and 28V CT specifications before procurement. Cross-reference datasheet revisions to validate compliance with current safety standards.
Selection Notes
Select this transformer when a compact, low-voltage solution with center-tapped capability is required for PCB-based designs. The 4.4VA rating suits light-load applications. Confirm that the physical dimensions and lead spacing align with the target PCB layout. Evaluate thermal performance requirements relative to the enclosed or open construction variant selected.
Part Context
This component belongs to the Hammond Manufacturing series of low voltage PCB mount transformers. These units are engineered for direct integration into electronic systems requiring reliable AC-to-AC isolation. The product line emphasizes standardized footprints and consistent electrical characteristics for industrial and commercial applications.
Replacement Considerations
Consult official cross-reference guides for verified substitute part numbers. Do not assume interchangeability based on similar ratings alone. Verify pinout compatibility and mounting hole alignment before substituting.
