161F56

Overview

The Hammond Manufacturing 161F56 is a low voltage power transformer designed for PCB mounting. It features a single primary winding rated for 115VAC input and a secondary configuration providing 56V center-tapped output at 80mA. With a maximum power rating of 4.4VA, this component utilizes a laminated core construction suitable for vertical through-hole installation on printed circuit boards.

Feature Summary

• Designed for direct vertical mounting onto printed circuit boards
• Provides isolated power conversion from standard AC line voltage to low voltage DC supply rails
• Utilizes a laminated core structure for efficient magnetic coupling

Applications

• Low voltage power supply circuits in electronic equipment
• Signal isolation stages requiring step-down transformation
• Control panel interfaces needing localized power distribution

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to ensure compatibility with required insulation classes and terminal configurations. Confirm that the 115V primary rating aligns with the local mains frequency and voltage standards of the deployment region before finalizing procurement orders.

Selection Notes

Select this component when a compact, board-mount solution is required for stepping down 115VAC to a 56V center-tapped rail. Ensure the PCB layout accommodates the vertical mounting height and pin spacing. Verify that the 4.4VA capacity meets the total load requirements of the downstream circuitry without exceeding thermal limits.

Part Context

This part belongs to the Hammond 161 Series, which encompasses a range of low voltage transformers for PCB applications. The series offers various power ratings and voltage combinations, allowing engineers to select standardized components for consistent mechanical and electrical performance across different product lines.

Replacement Considerations

Consult official substitution lists for equivalent transformers with matching VA ratings and pinouts. Verify that any alternative part maintains the same center-tapped secondary configuration and vertical mounting footprint to ensure mechanical compatibility.
