162G120

Overview

The Hammond Manufacturing 162G120 is a laminated core power transformer designed for through-hole PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation, allowing flexible voltage configuration. The secondary side offers dual windings supporting parallel or series connections to provide either 60V at 200mA (parallel) or 120V Center-Tap at 100mA (series). With a 12 VA power rating, this low-profile unit is engineered for reliable low-voltage AC power conversion in electronic assemblies requiring standard isolation.

Feature Summary

• Dual primary winding design supports both 115 VAC and 230 VAC input configurations
• Dual secondary windings enable versatile output options via parallel or series connection
• Low-profile construction optimized for direct through-hole PCB mounting
• Laminated core technology ensures efficient magnetic coupling and power transfer

Applications

• Low-voltage AC power supply stages in industrial control panels
• Signal processing equipment requiring isolated power inputs
• Electronic test and measurement devices
• Consumer electronics utilizing standard line voltages

Procurement Notes

Verify the specific secondary configuration required for your circuit, as the part supports both parallel and series outputs. Confirm that the physical dimensions of the through-hole footprint align with your PCB layout constraints. Ensure the operating temperature range meets your application's environmental specifications before finalizing procurement.

Selection Notes

Select this component when a compact, low-voltage transformer is needed for PCB integration. The dual primary capability simplifies global product designs by accommodating different mains voltages without changing hardware. Consider the 12 VA rating to ensure sufficient power headroom for downstream components while maintaining a small form factor.

Part Context

This transformer belongs to Hammond Manufacturing's general-purpose power transformer lineup, known for robust construction and standardized pinouts. It serves as a fundamental power conversion element in systems requiring galvanic isolation between the mains input and sensitive low-voltage circuitry, replacing older relay-based or non-isolated solutions.

Replacement Considerations

Direct substitutes must match the 12 VA rating, dual primary/secondary winding structure, and through-hole mounting style. Verify that alternative parts maintain the same physical envelope to fit existing PCB footprints. Check if competitor models offer identical center-tap capabilities if that specific output is critical to the design.
