Procurement Notes
Verify the specific part number against official Hammond Manufacturing documentation to confirm technical specifications. Ensure compatibility with your system's voltage requirements and physical mounting constraints before procurement. Cross-reference datasheets for accurate dimensional and electrical data.
Selection Notes
Select this component when a compact, low voltage transformer is required for direct PCB integration. Consider the 36 VA power rating and 20 VAC center-tapped output to ensure it meets the load requirements of the target circuit. Verify that the solder pin termination style aligns with the PCB layout design.
Part Context
This transformer belongs to the category of low voltage power transformers manufactured by Hammond Manufacturing. It is distinct from their industrial enclosure and toroidal transformer lines, focusing specifically on surface-mount or through-hole PCB integration for consumer and industrial electronics.
Replacement Considerations
Consult official Hammond Manufacturing substitution guides for verified equivalent part numbers. Do not assume generic transformers are compatible without verifying electrical ratings and physical dimensions.
