162H120

Overview

The Hammond Manufacturing 162H120 is a low voltage power transformer designed for printed circuit board (PCB) mounting. It features a low profile construction with a split bobbin design and dual windings that are non-concentrically wound. The unit operates on 50/60 Hz current and provides a 20VA capacity. Primary winding options include 115V or 230VAC, configurable in parallel or series. Secondary outputs offer multiple voltage choices ranging from 5 to 120VAC RMS, with specific configurations such as 120V center tap at 0.16A.

Feature Summary

• Low profile PCB mount design
• Split bobbin construction
• Dual non-concentrically wound secondaries

Applications

• Industrial control panels
• Test and measurement equipment
• Consumer electronics power supplies

Procurement Notes

Verify the exact secondary voltage configuration required for your application, as this model supports multiple output options. Confirm primary voltage compatibility with your local power standards. Check datasheet for precise pinout and mounting hole dimensions to ensure mechanical fit within your enclosure design.

Selection Notes

Select this component when space constraints require a low-profile transformer. Ensure the required VA rating meets system load demands. Consider the available secondary voltage options to match downstream circuit requirements without additional conversion stages.

Part Context

This transformer belongs to Hammond's line of low voltage PCB mount units. It is part of a family offering various VA sizes from 1.1 to 36VA. The design emphasizes compactness and electrical isolation for safe operation in sensitive electronic environments.

Replacement Considerations

Direct substitutes must match the 20VA rating, 50/60Hz frequency, and compatible physical footprint. Verify that alternative models support the same primary voltage configurations and provide equivalent secondary voltage options.
