161J10-BULK

Overview

The Hammond Manufacturing 161J10-BULK is a low-voltage power transformer designed for printed circuit board (PCB) mounting. It features an 115V primary voltage input and delivers a 10VA output capacity. The secondary winding provides a 10V center-tapped configuration, supporting a maximum current of 1A per leg. This component is engineered for direct integration into electronic assemblies requiring reliable step-down conversion from standard line voltages to lower operational levels.

Feature Summary

• Designed for direct PCB mounting applications
• Provides isolated low-voltage AC output
• Features a center-tapped secondary winding configuration

Applications

• Low-voltage control circuits
• Power supply stages for electronic devices
• Industrial automation equipment

Procurement Notes

Verify the specific suffix or packaging designation when ordering, as 'BULK' indicates loose unit delivery rather than tape-and-reel or boxed configurations. Confirm that the 115V primary rating aligns with your local mains frequency and voltage standards. Ensure PCB footprint dimensions match the datasheet specifications before finalizing procurement to avoid mechanical integration issues.

Selection Notes

Select this model when a compact, through-hole mounted transformer is required for 115VAC to 10VCT conversion. Consider the 10VA power limit to ensure it meets the load requirements of the downstream circuitry. Evaluate thermal management needs based on the open construction style, which may require adequate airflow within the enclosure compared to encapsulated alternatives.

Part Context

This part belongs to Hammond Manufacturing's series of general-purpose power transformers. These components are widely utilized in industrial and commercial electronics where robust performance and standard pinout configurations are necessary. The 161J10 represents a specific variant optimized for 10VA applications, distinguishing it from higher or lower power ratings within the same product family.

Replacement Considerations

Consult official cross-reference lists for electrically equivalent transformers with matching VA ratings and pinouts. Verify that any substitute maintains the same insulation class and safety certifications. Ensure physical dimensions and mounting hole patterns are compatible with existing PCB layouts if direct replacement is intended.
