Power Transformers Procurement Notes

Verify the specific datasheet revision and marking codes against official Tamura documentation before procurement. Confirm that the required output configuration matches the parallel or series winding capabilities. Ensure mechanical fit within the assembly envelope considering the 38mm seated height. Check for any updated regulatory compliance certifications relevant to the target market.

Power Transformers Selection Notes

Select this component when a 12VA power rating and 115V primary input are required. Choose the 3FS-512 over other models if dual secondary voltages of 6.3V and 12.6V are necessary. Consider the through-hole mounting style and PC pin termination for compatibility with existing PCB layouts. Evaluate the physical dimensions against available space constraints in the final product design.

Power Transformers Part Context

This transformer belongs to the Tamura 3FS series of power transformers. The series offers various power ratings and voltage configurations. The 3FS-512 specifically addresses applications requiring moderate power delivery with multiple secondary voltage options. It is designed for reliability in standard industrial and commercial environments.

Power Transformers Replacement Considerations

The 3FD-512 is a related model within the same series offering similar power characteristics but with a three-flange dual primary configuration. Verify mounting hole patterns and terminal types when substituting between these variants.
