161F34

Overview

The Hammond Manufacturing 161F34 is a low voltage PCB mount power transformer featuring a laminated core and vertical split bobbin design. It operates with a 115V primary winding and provides a 34V center-tapped secondary output at 125mA, delivering a 4.4VA power rating. The component utilizes through-hole mounting for secure board integration.

Feature Summary

• Vertical mount configuration with split bobbin construction
• Laminated core architecture for efficient power transfer
• Center-tapped secondary winding capability

Applications

• Low voltage electronic circuit power supplies
• Printed circuit board mounted equipment
• Control panel power distribution

Procurement Notes

Verify the specific electrical ratings against project requirements before ordering. Confirm that the 115V primary voltage matches the available supply line. Ensure the PCB layout accommodates the through-hole pin spacing and physical dimensions of the vertical mount package to prevent assembly conflicts.

Selection Notes

Select this model when a compact, vertically oriented transformer is required for space-constrained designs. The 4.4VA rating suits low-power applications. Verify that the 34V CT secondary meets the downstream rectification and regulation needs of the target circuit topology.

Part Context

This component belongs to the Hammond 161 series of low voltage PCB mount transformers. The series offers various voltage and VA options within a standardized vertical form factor, allowing designers to maintain consistent mechanical layouts while adjusting electrical specifications for different power requirements.

Replacement Considerations

Direct substitutes include other Hammond 161 series models with identical 4.4VA ratings and 115V primaries but differing secondary voltages, such as the 161E40 or 161G28, provided the voltage output aligns with the application needs.
