164G120

Overview

The Hammond Manufacturing 164G120 is a low-voltage PCB mount power transformer featuring a laminated core and low-profile design. It operates with a single primary winding rated for 115 VAC. The secondary configuration provides dual windings capable of series or parallel connections, delivering 12 VA of power. Electrical ratings include 120 VAC center-tapped at 0.1 A in series mode, or 60 VAC at 0.2 A in parallel mode. The component utilizes through-hole mounting and measures 1.63 inches in length, 1.31 inches in width, and 1.31 inches in height.

Feature Summary

• Low-profile construction designed for space-constrained printed circuit board applications
• Laminated core technology ensures efficient power transformation
• Flexible secondary winding options allowing series or parallel connectivity
• Through-hole mounting style for secure PCB integration

Applications

• Low voltage electronic equipment requiring isolated AC power
• Control panels utilizing PCB-mounted transformers

Procurement Notes

Verify the exact electrical configuration required for your application before procurement. Confirm whether series or parallel secondary connection is needed to match voltage and current specifications. Ensure the PCB layout accommodates the specified through-hole pin spacing and physical dimensions. Cross-reference the manufacturer datasheet for insulation class and thermal limits to guarantee compatibility with your system's operating environment.

Selection Notes

Select this model when a compact, low-voltage transformer is necessary for PCB assembly. Consider the 12 VA rating against total system load requirements. Evaluate the physical footprint constraints against the 1.63 x 1.31 x 1.31 inch dimensions. Determine if the 115 VAC primary input matches available supply voltages. Assess whether the flexible secondary wiring options suit the circuit topology.

Part Context

This component belongs to the Hammond 164 series of power transformers. The series is characterized by low-voltage outputs and PCB-mount form factors. Similar models in the lineup may vary in VA rating, voltage configurations, or physical size while maintaining the same general mounting style and core technology.

Replacement Considerations

Direct substitutes must match the 12 VA rating, 115 VAC primary, and compatible secondary configurations. Verify that alternative components fit the same PCB footprint and maintain similar thermal performance. Consult manufacturer cross-reference lists for verified equivalent part numbers.
