162J120

Overview

The Hammond Manufacturing 162J120 is a low-voltage power transformer designed for printed circuit board (PCB) mounting. It features dual primary windings rated for 115 VAC and 230 VAC input, providing versatile compatibility with standard electrical frequencies of 50/60 Hz. The secondary output delivers 120 VAC center-tapped at 300 mA, resulting in a total power rating of 36 VA. Constructed with a low-profile design, the unit measures 2.63 inches in length, 2.19 inches in width, and 1.56 inches in height. It utilizes solder pin termination for secure through-hole installation and operates within a temperature range of 0°C to +130°C.

Feature Summary

• Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages for flexible deployment across different regional power standards.
• Low-profile physical construction facilitates integration into space-constrained electronic assemblies requiring compact PCB-mounted solutions.
• Center-tapped secondary output provides precise voltage regulation suitable for sensitive control circuits and signal processing applications.

Applications

• Industrial control panels requiring isolated low-voltage power distribution
• Electronic instrumentation systems needing stable AC signal generation
• Automated machinery control boards utilizing center-tapped transformer inputs

Procurement Notes

Verify that the specific order matches the manufacturer part number 162J120 to ensure correct voltage ratings and physical dimensions. Confirm that the application environment remains within the specified operating temperature range of 0°C to +130°C. Ensure that the PCB layout accommodates the through-hole solder pin termination style and the component's footprint dimensions prior to procurement.

Selection Notes

Select this component when a low-profile, board-mount transformer is required for 50/60 Hz applications. The dual primary winding allows selection between 115 VAC or 230 VAC input based on system requirements. The 36 VA rating and 120 VAC center-tapped output define its capacity for driving specific load currents. Consider the physical height constraint of 1.56 inches when designing the enclosure clearance for the assembly.
