Procurement Notes

Verify the specific ordering suffix and packaging configuration when placing orders, as availability may vary between tape-and-reel and cut-tape formats. Confirm current lead times directly with authorized distributors, as production schedules are subject to change. Ensure that the procurement channel is an authorized supplier to guarantee component authenticity and compliance with environmental regulations such as RoHS3.

Selection Notes

Select this component when designing circuits requiring integrated isolation and data signaling in a single surface-mount package. The EP10 form factor is suitable for space-constrained layouts. Verify that the 155µH inductance and specific turns ratio align with the system's impedance matching and power transfer requirements. Ensure the operating temperature range meets the environmental conditions of the final application.

Part Context

This part belongs to the Pulse Transformers category from Pulse Electronics, specifically tailored for board-mounted applications. It serves as a critical passive component in modern networking hardware, enabling efficient power and data transmission over standard Ethernet cabling while maintaining galvanic isolation between network segments.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the EP10 footprint, 155µH inductance, and 1:0.273:0.682 turns ratio precisely.
