164D120

Overview

The Hammond Manufacturing 164D120 is a low-voltage PCB mount power transformer with a single primary winding rated for 115 VAC. It features dual secondary windings providing a center-tapped output of 120 VAC at 0.01 A, resulting in a total power rating of 1.1 VA. Designed for through-hole installation, the unit measures 1.38 inches in length, 1.13 inches in width, and 1.31 inches in height. The component operates within a temperature range of 0°C to +130°C and utilizes solder pin termination.

Feature Summary

• Low profile design optimized for compact printed circuit board mounting applications
• High isolation between primary and secondary windings for enhanced safety
• Dual secondary winding configuration enabling center-tapped voltage outputs

Applications

• Low voltage electronic control circuits
• Industrial instrumentation power supplies
• Consumer electronics requiring isolated AC power

Procurement Notes

Verify that the specific order matches the 164D120 designation to ensure correct electrical parameters, particularly the 1.1 VA rating and 120V CT secondary specification. Confirm that the procurement documentation references the Hammond Manufacturing manufacturer code and RoHS compliance status as listed in official product catalogs. Ensure the package type aligns with standard bulk distribution formats for this series.

Selection Notes

Select this component when a compact, low-power transformer is required for 115VAC input systems. The 1.1 VA rating suits applications with minimal current demands. Consider the physical dimensions of 1.38 x 1.13 x 1.31 inches for PCB layout constraints. Verify that the operating temperature range up to 130°C meets the environmental requirements of the target assembly.

Part Context

This part belongs to the Hammond 164 series of low-voltage PCB mount transformers. The series offers various voltages and VA ratings, sharing common mechanical footprints and mounting styles. The 164D120 represents a specific variant within this family, distinguished by its 1.1 VA capacity and 120V center-tapped secondary output configuration.

Replacement Considerations

Cross-reference with other Hammond 164 series models such as 164F120 or 164E20 if different voltage or current ratings are needed. Ensure any substitute maintains the same 115VAC primary rating and through-hole mounting style to preserve PCB compatibility.
