H2005ANLT

Overview

The H2005ANLT is a two-port audio/signal transformer module designed for 100Base-TX applications with Power over Ethernet (PoE) support. It features surface-mount technology (SMD) termination and operates within a frequency range of 1 MHz to 100 MHz. The component has an inductance of 350 uH, a primary DC resistance of 3.5 Ohms, and provides 1.5 kV isolation voltage. It supports dual channels and functions reliably between -40°C and +85°C.

Feature Summary

• Supports Power over Ethernet (PoE) functionality for integrated power and data transmission
• Provides electrical isolation via 1.5 kV insulation voltage rating
• Optimized for 100Base-TX network standards with dual-channel capability

Applications

• 100Base-TX Ethernet network interface circuits
• Power over Ethernet (PoE) powered devices
• Telecommunications signal processing modules
• LAN transformer integration in embedded systems

Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to procurement, as manufacturer specifications may be updated. Confirm that the SMD gull-wing package dimensions align with your PCB footprint requirements. Ensure the 3.5 Ohm primary DC resistance meets your circuit's power loss constraints. Validate that the 1.5 kV isolation rating satisfies your safety isolation standards for the intended application environment.

Selection Notes

Select this component when designing for 100Base-TX standards requiring PoE integration. The 350 uH inductance value is critical for maintaining signal integrity at specified frequencies. Consider the 1.5 kV isolation voltage if high-voltage separation between ports is required. The SMD form factor suits automated assembly processes, but verify thermal performance within the -40°C to +85°C operating range for harsh environments.

Part Context

This part belongs to Pulse Electronics' LAN transformer portfolio, specifically engineered for telecommunication and networking applications. It serves as a magnetic module for Ethernet interfaces, combining magnetics and common-mode chokes into a single surface-mount unit. The design facilitates compact board layouts while ensuring signal fidelity and electrical safety in compliant network hardware.

Replacement Considerations

The H2005ANLT is functionally similar to the H5020NLT; however, the latter lacks PoE support. Verify compatibility before substitution, as the absence of PoE capabilities will alter circuit functionality. No other direct public substitutes are confirmed in available documentation.
