HD8004FNLT

Overview

The HD8004FNLT is a single-port HDBase-T pulse transformer module manufactured by Pulse Electronics. Designed for surface mount technology, this component features an inductance of 180µH and operates within a frequency range of 1 MHz to 500 MHz. It supports PoE+ applications and maintains a 1:1 turns ratio. The physical dimensions are 15 mm in length, 13.7 mm in width, and 5.72 mm in height. The device functions reliably between 0°C and +70°C, complies with RoHS standards, and is supplied in cut tape or reel packaging.

Feature Summary

• Supports HDBase-T transmission protocols with integrated PoE+ capabilities
• Optimized for high-frequency signal integrity across the 1 MHz to 500 MHz spectrum
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• HDBase-T network interface modules
• PoE-powered audio and video transmission systems
• Single-port LAN isolation circuits

Procurement Notes

Verify the specific suffix 'LT' indicates the tape-and-reel or cut-tape packaging configuration rather than a functional variant. Confirm that the 180µH inductance value aligns with the target HDBase-T circuit requirements. Ensure the operating temperature range of 0°C to +70°C meets the environmental specifications of the end application. Cross-reference the manufacturer part number with distributor codes to ensure correct sourcing.

Selection Notes

Select this component when designing HDBase-T interfaces requiring PoE+ support and a 180µH primary inductance. Compare against the HD8004FNL if tube packaging is preferred over tape-and-reel. Consider the HD8005FNL if a different inductance value is required for specific impedance matching. Ensure the SMD footprint matches the 15mm x 13.7mm x 5.72mm mechanical constraints of the design.

Part Context

This part belongs to the HD series of LAN transformers from Pulse Electronics, specifically engineered for HDBase-T applications. It serves as a critical isolation component in digital AV distribution networks. The model distinguishes itself through its specific 180µH inductance and PoE+ compatibility, differentiating it from standard Ethernet transformers or other variants within the same family that may offer different electrical characteristics.

Replacement Considerations

HD8004FNL is a direct substitute offering identical electrical specifications but utilizes tube packaging instead of tape-and-reel.
