Pulse Transformers Procurement Notes

Verify the specific suffix T9 against official Bel Fuse documentation to confirm pinout and mechanical compatibility. Ensure the source document explicitly lists this part number as active or available. Cross-reference the datasheet for moisture sensitivity level requirements during storage and handling procedures.

Pulse Transformers Selection Notes

Select this component when a Gigabit Ethernet solution is required with a standard footprint similar to the AM-F variant. Consider the extended operating temperature range down to -40°C for industrial environments. Verify that the 350 µH inductance meets the specific impedance matching requirements of the target PHY transceiver.

Pulse Transformers Part Context

This part belongs to the S558 series of LAN discrete transformer modules from Bel Fuse. These modules integrate common mode chokes and center-tapped transformers into a single compact package. They are engineered to reduce board space and simplify the design of Ethernet interfaces compared to discrete components.
