Overview
The Hammond Manufacturing 161H16 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 16 VAC center-tapped output. The unit has a power rating of 24 VA with a secondary current capacity of 1.5 A. Constructed for through-hole installation, it utilizes solder pin termination. The component operates within a temperature range of 0°C to +130°C at a frequency of 60 Hz.
Feature Summary
- Dual secondary winding architecture supporting center-tapped configurations
- Through-hole PCB mounting style with solder pin terminations
- Low voltage operation suitable for direct board integration
Applications
- Power supply circuits requiring 16V AC center-tapped input
- Industrial control systems utilizing low voltage AC distribution
- Electronic equipment needing isolated power transformation on PCBs
Procurement Notes
Verify RoHS compliance status as documentation indicates non-compliance. Confirm that the specific batch meets project environmental requirements. Ensure the 115V primary voltage matches the local mains supply. Validate that the 24 VA rating provides sufficient headroom for the intended load current without thermal overload during continuous operation.
Selection Notes
Select this model when a 16V AC center-tapped output is required from a 115V source. The 24 VA rating supports up to 1.5 A per secondary leg. Consider the physical dimensions and through-hole footprint compatibility with the target PCB layout. Evaluate thermal management needs given the operating temperature limits and enclosed application scenarios.
Part Context
This component belongs to the Hammond 161 series of low voltage power transformers. It shares design characteristics with variants like the 161E40 and 161G28, differing primarily in voltage ratings and power capacities. The series is standardized for general-purpose electrical enclosure applications requiring reliable AC-to-AC voltage conversion.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing footprints if considering alternative manufacturers. Ensure replacement units match the 115V primary and 16V CT secondary specifications.
