Procurement Notes
Verify the specific manufacturer part number against official Pulse Electronics documentation to ensure compatibility with target circuit designs. Confirm that the surface mount package dimensions and pinout align with the printed circuit board layout requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the system's thermal constraints.
Selection Notes
Select this component for 10Base-T Ethernet interfaces requiring galvanic isolation. The 160 uH inductance and specified impedance values support standard IEEE802.3 signaling. Consider the unshielded nature when planning PCB layout to manage electromagnetic interference. Verify that the surface mount footprint matches available board space and soldering capabilities.
Part Context
This component belongs to the Pulse Electronics audio and signal transformers category. It serves as an isolation transformer specifically engineered for data interface applications. The product line targets networking hardware where reliable signal transmission and electrical separation are critical for system integrity.
Replacement Considerations
Consult official distributor databases for cross-reference information. Verify functional equivalence regarding inductance, impedance, and physical dimensions before substitution.
