161D16

Overview

The Hammond Manufacturing 161D16 is a low-voltage power transformer designed for printed circuit board (PCB) mounting. It features a single primary winding rated at 115 VAC and operates at a frequency of 60 Hz. The secondary configuration provides a center-tapped output with dual voltage ratings: 16 VAC at 55 mA and 8 VAC at 110 mA. The unit has a total power rating of 1 VA. It utilizes through-hole solder pin termination for secure electrical connections to the PCB.

Feature Summary

• Single primary winding construction for standard AC input
• Dual secondary voltage outputs with center tap
• Low voltage design suitable for sensitive electronics
• Through-hole solder pin termination

Applications

• Low-power electronic control circuits
• Signal processing equipment requiring isolated power
• Industrial automation components
• Consumer electronics power supplies

Procurement Notes

Verify that the specific application requires the exact 1 VA rating and the specified secondary voltages of 16V/8V CT. Confirm that the PCB layout supports the through-hole footprint dimensions provided in the datasheet. Ensure the operating environment remains within the standard temperature range defined by the manufacturer for this component series.

Selection Notes

Select this model when a compact, low-power transformer is needed for direct PCB integration. It is appropriate for designs requiring a single primary input and split secondary rails derived from a center tap. Consider the physical size constraints and the thermal characteristics associated with a 1 VA laminated core transformer before finalizing the design.

Part Context

This component belongs to the 161 series of low-voltage transformers manufactured by Hammond Manufacturing. These units are characterized by their small form factor and suitability for panel or board mounting applications. The series offers various voltage configurations to accommodate different low-power requirements in industrial and commercial settings.

Replacement Considerations

Direct substitutes include other Hammond 161 series transformers with matching 1 VA ratings and compatible secondary voltage taps. Verify that any replacement part maintains the same 115 VAC primary specification and through-hole pin configuration to ensure mechanical and electrical compatibility.
