Overview
The Hammond Manufacturing 166K12 is a laminated core power transformer with a 14.4 VA rating. It features a single primary winding rated for 115 VAC at 60 Hz and a center-tapped secondary output of 12 VAC at 1.2 A. Designed for chassis mounting, it utilizes wire lead terminations. The unit operates within a temperature range of 0°C to +130°C and is suitable for low-voltage isolation applications involving filament and LV rectifier circuits.
Feature Summary
- Center-tapped secondary winding configuration
- Laminated core construction
- Chassis mounting style
- Low voltage isolation design
Applications
- Filament power supply circuits
- Low voltage rectifier applications
- Industrial control equipment
- General purpose low voltage isolation
Procurement Notes
Verify the specific datasheet version for the 166K12 to confirm exact dimensional tolerances and terminal specifications. Ensure compatibility with existing chassis mounting holes and wire gauge requirements. Confirm regulatory compliance status such as UL or CE marking if required for your specific deployment region before finalizing procurement.
Selection Notes
Select this component when a 14.4 VA capacity is sufficient for the load. The 115 VAC primary input dictates suitability for standard North American line voltages. The center-tapped 12 VAC secondary is ideal for full-wave rectification requiring a ground reference. Verify that the 1.2 A current rating meets the maximum continuous load requirements of the target circuit.
Part Context
This part belongs to the Hammond 166 series of industrial power transformers. These units are characterized by their robust laminated steel cores and standardized chassis mounting profiles. The series provides reliable isolation for various electronic applications requiring stable low voltage outputs from standard AC mains sources.
Replacement Considerations
The 166K12B is a related variant in the same series but offers different electrical ratings (18.9 VA, 12.6V secondary). Verify that the higher power rating and voltage difference do not impact the target circuit design before substituting.
