Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and tape specifications. Confirm that the selected variant matches the required RoHS compliance status and moisture sensitivity level for the intended assembly process. Cross-reference the part number with official distributor catalogs to validate availability and lead times prior to finalizing procurement plans.

Selection Notes

Select this component for designs requiring standard 10/100 Base-T isolation and signal conditioning. Ensure the PCB footprint accommodates the specified 12.70mm x 9.09mm dimensions and allows for the 5.99mm maximum height clearance. Verify compatibility with the target impedance requirements and thermal operating conditions defined in the official datasheet.

Part Context

This model belongs to the Pulse Electronics LAN transformer series, specifically engineered for high-speed digital signal integrity in networking equipment. It serves as a critical interface component between the physical layer transceiver and the external twisted-pair cabling, providing necessary galvanic isolation and common-mode noise rejection.

Replacement Considerations

The H1199FNLT is documented as a parameter-equivalent substitute. Verify mechanical fit and electrical specifications before implementation.
