- Laminated core design for efficient low voltage transformation
- Center-tapped secondary winding configuration
- Wire lead termination style
Applications
- Industrial control panels
- Low voltage circuit powering
- Filament supply applications
Procurement Notes
Verify the specific ordering suffix to ensure the correct voltage and configuration match the system requirements. Confirm that the chassis mounting style and wire lead termination are compatible with the existing assembly infrastructure. Check RoHS compliance status if environmental regulations apply to the project. Ensure the operating temperature range meets the thermal conditions of the intended enclosure environment.
Selection Notes
Select this component when a 25 VA isolation transformer is required for 115 VAC input systems. The 25 VAC center-tapped output is suitable for circuits requiring dual polarity or rectification. Consider the physical dimensions and chassis mounting requirement during the mechanical design phase. Verify that the 1 A secondary current rating satisfies the load demands of the connected control components.
Part Context
The 167J25 belongs to the Hammond 167 series of industrial control transformers. This series provides enclosed, chassis-mount solutions for general-purpose power conversion. The model represents a standard low-voltage variant within the product line, offering reliable performance for control panel applications where space efficiency and defined electrical characteristics are prioritized.
Replacement Considerations
No public substitute part numbers are documented for this component.
