Procurement Notes

Verify the specific suffix '4J41DT' against official Abracon documentation to confirm pinout configuration and terminal type. Ensure the selected variant matches the required operating temperature range and DC resistance specifications for the target circuit design. Cross-reference datasheet revision dates to validate current manufacturing status and compliance details.

Selection Notes

Select this component for designs requiring integrated LAN isolation and signal conditioning in a single SMD footprint. Consider the 24-pin gull wing package for standard surface mount assembly processes. Evaluate the 350 µH inductance and specified DC resistances against the PHY chip requirements to ensure signal integrity and impedance matching for Gigabit Ethernet speeds.
