Procurement Notes
Verify the specific voltage configuration and physical dimensions against the official Hammond Manufacturing datasheet before integration. Confirm that the 115V primary input matches the target system supply. Ensure the chassis mounting requirements align with the mechanical specifications provided in the product documentation.
Selection Notes
Select this model when a low-voltage, center-tapped secondary is required for 115VAC primary systems. The 18VA rating suits light industrial loads. Consider the chassis mount form factor and wire lead termination method for PCB or terminal block connectivity. Verify thermal operating limits for the intended environment.
Part Context
This component belongs to the Hammond Manufacturing 166 series of industrial control transformers. The series offers various power ratings and voltage configurations. The 166J18 specifically addresses applications requiring 18VA capacity with a 18VCT secondary output. It is categorized under power transformers for industrial use.
Replacement Considerations
Consult the official Hammond Manufacturing cross-reference documentation for verified substitute part numbers. Do not assume compatibility based on similar electrical ratings alone. Verify mechanical fit and pinout alignment if considering alternatives from other manufacturers.
