162H12

Overview

The Hammond Manufacturing 162H12 is a low voltage PCB mount power transformer designed for through-hole installation. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz. The unit provides a secondary output of 12.6 VAC center-tapped, delivering a maximum current of 1.6 A with a total power rating of 20 VA. Physical dimensions are 1.63 inches in length, 1.31 inches in width, and 1.31 inches in height. The component utilizes a laminated core construction and solder pin termination style.

Feature Summary

• Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages
• Low profile design optimized for direct PCB mounting applications
• Center-tapped secondary output provides flexible voltage distribution

Applications

• Low voltage AC power supply circuits
• Electronic equipment requiring isolated power conversion
• Control panel internal power distribution

Procurement Notes

Verify the specific secondary voltage and current ratings against project requirements, as the 162 series offers multiple variants. Confirm that the through-hole termination style matches the target PCB footprint. Ensure the operating frequency aligns with the 50/60 Hz specification. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this model when a 20 VA capacity is required for low voltage applications. The dual primary winding allows compatibility with different regional mains voltages without hardware changes. Consider the physical height constraint of 1.31 inches for enclosure clearance. This component is suitable for designs needing a center-tapped secondary source from a standard PCB layout.

Part Context

The 162H12 belongs to the Hammond 162 series of low voltage PCB mount transformers. This series includes various power ratings ranging from 1.1 VA to 36 VA. All models in the series share similar low-profile mechanical characteristics and dual primary winding capabilities. The series is designed for general-purpose power transformation in compact electronic assemblies.

Replacement Considerations

Cross-reference other Hammond 162 series part numbers for alternative voltage or current ratings. Verify mechanical footprint compatibility before substituting with components from different manufacturers. Ensure electrical isolation ratings meet safety standards for the intended application.
