164J120

Overview

The Hammond Manufacturing 164J120 is a low voltage power transformer designed for PCB mounting. It features a laminated core construction with dual primary windings supporting 115 VAC and 230 VAC inputs, configurable via parallel or series connections. The secondary output provides 120 VAC center-tapped at 300 mA, yielding a total apparent power rating of 36 VA. The unit utilizes solder pin termination for through-hole installation. Physical dimensions are 2.63 inches in length, 2.19 inches in width, and 1.56 inches in height. It operates within a temperature range of 0°C to +130°C.

Feature Summary

• Dual primary winding configuration allows flexible input voltage selection between 115V and 230V AC systems.
• Low profile design facilitates integration into space-constrained printed circuit board assemblies.
• Center-tapped secondary output provides balanced voltage distribution for specific rectification requirements.

Applications

• Low voltage power supply circuits requiring isolated AC-to-AC conversion
• Industrial control panels utilizing PCB-mounted transformers
• Equipment requiring 120V center-tapped secondary outputs

Procurement Notes

Verify the specific datasheet version for the 164J120 to confirm exact winding configurations and insulation class ratings. Ensure that the selected mounting orientation accommodates the physical dimensions of 2.63 x 2.19 x 1.56 inches. Confirm that the operating environment remains within the specified 0°C to +130°C thermal limits to maintain performance integrity and safety compliance.

Selection Notes

Select this component when a low-profile, board-mount solution is required for 36 VA applications. The dual primary winding capability makes it suitable for global deployment where input voltages vary between 115V and 230V. Consider the through-hole solder pin termination method during PCB layout design to ensure adequate clearance and mechanical stability for the laminated core structure.
