160D16

Overview

The Hammond Manufacturing 160D16 is a low voltage PCB mount power transformer featuring a split bobbin design. It accepts a universal dual primary input of 115/230VAC and provides a secondary output of 16V C.T. at 55mA, with a total power rating of 1VA. The component utilizes low primary-to-secondary coupling to eliminate the need for an electrostatic shield. This vertical mount transformer is part of the 160 series, designed for efficient board mounting in compact electronic assemblies requiring isolated AC power conversion.

Feature Summary

• Split bobbin construction for vertical PCB mounting
• Low primary-to-secondary coupling eliminating electrostatic shield requirement
• Universal dual primary input capability for 115/230VAC operation

Applications

• Low voltage AC power supply circuits
• Control panel transformers
• Electronic equipment requiring isolated AC power
• Board-mounted power distribution systems

Procurement Notes

Verify the specific secondary voltage configuration and current rating against the application requirements before ordering. Confirm that the 1VA power rating and 16V C.T. output match the load specifications. Ensure the PCB footprint and pin spacing are compatible with the manufacturing layout. Check for any specific mounting hardware requirements associated with the vertical split bobbin design.

Selection Notes

Select this transformer when a compact, vertically mounted solution is required for low-power AC applications. The universal dual primary allows flexibility across different regional line voltages without changing components. Consider the 1VA limit to ensure it meets the downstream circuit's power consumption needs. The absence of an electrostatic shield simplifies the design but requires adherence to the specified coupling characteristics.

Part Context

The 160D16 belongs to Hammond Manufacturing's 160 series of low voltage PCB mount transformers. This series offers various output voltages ranging from 5 to 120VAC RMS and multiple VA sizes. The 160D16 specifically addresses the need for a 16V center-tapped output in a small form factor, fitting within the broader category of board-mount power components used in industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 1VA rating, 16V C.T. secondary, and 115/230V primary input. Verify physical dimensions and pinout compatibility for direct replacement. Other models in the 160 series may offer different voltages or VA ratings but share similar mounting characteristics.
