Procurement Notes

Verify the specific suffix against official Pulse Electronics documentation to confirm package type and reel specifications. Ensure the selected variant matches the required non-PoE configuration and SMD termination style for the target design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability and compliance status before finalizing procurement orders.

Selection Notes

Select this component when designing for standard 100 Mbps Ethernet connections requiring integrated magnetics. The single-channel architecture suits simple PHY interfaces without Power over Ethernet requirements. Consider the thermal operating limits and physical footprint constraints during layout planning to ensure reliable performance in space-constrained embedded networking devices.

Part Context

This device belongs to the HM series of LAN transformers from Pulse Electronics. It serves as a critical passive component for signal integrity and noise suppression in Ethernet networks. The module integrates primary and secondary windings with center taps to facilitate proper differential signaling and common-mode rejection for compliant data transmission.

Replacement Considerations

HM0068ANLT is a documented substitute variant within the same family.
