Power Transformers Procurement Notes

Verify the specific suffix code on the component label against the datasheet to confirm exact electrical characteristics, as variations may exist within the product family. Ensure the procurement documentation explicitly states compliance with RoHS3 regulations and UL safety standards before finalizing orders. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times, as stock levels fluctuate.

Power Transformers Selection Notes

Select this model when a 12VA capacity is required with flexible secondary voltage options. Verify that the PCB layout accommodates the specified physical footprint and pin spacing. Confirm that the operating environment does not exceed the thermal limits defined in the datasheet. Ensure the input voltage matches the dual primary rating for proper operation.

Power Transformers Part Context

The FS120-100 belongs to Triad Magnetics' Split Pack series, which offers versatile bobbin transformers for printed circuit board applications.
