H1062NLT

Overview

The H1062NLT is a surface-mount LAN transformer module manufactured by Pulse Electronics, designed for 10/100Base-TX applications. It features four isolated ports with a 1:1 turns ratio for both transmitter and receiver circuits. The component operates within a temperature range of 0°C to +70°C and provides 1.5 kV isolation voltage. Key electrical parameters include an inductance of 350 µH and a secondary coil impedance of 0.65 Ohms. The physical dimensions are 28.58 mm in length, 12.19 mm in width, and 5.84 mm in height. It utilizes SMD/SMT termination and is packaged in tubes.

Feature Summary

• Provides four isolated Ethernet channels for simultaneous data transmission and reception
• Supports standard 10/100Base-TX network protocols without Power over Ethernet capabilities
• Features encapsulated construction for enhanced environmental protection and signal integrity

Applications

• 10/100 Mbps Ethernet network interface cards
• Industrial communication gateways requiring robust signal isolation
• Embedded systems with integrated Ethernet connectivity

Procurement Notes

Verify the specific package type upon ordering, as distribution sources may list tube or tape-and-reel variants depending on the suffix or distributor configuration. Confirm RoHS compliance status and lead times directly with authorized suppliers, as manufacturing cycles can vary. Ensure the selected variant matches the required PCB footprint and thermal specifications for the target application environment.

Selection Notes

Select this component for designs requiring multi-port isolation in compact form factors. It is suitable for non-PoE Ethernet interfaces where space efficiency is critical. Consider the operating temperature range and insulation voltage requirements when evaluating suitability for industrial or commercial environments. Compare pinout configurations against existing schematics to ensure compatibility.

Part Context

This part belongs to Pulse Electronics' LAN Transformer series, specifically engineered for high-density networking solutions. It complements other single and dual-port modules by offering quad-channel integration, reducing board space and assembly complexity. The product line emphasizes reliability and signal quality for standard twisted-pair copper cabling applications.

Replacement Considerations

The H1062NL is a related variant from the same manufacturer family. Verify mechanical dimensions and pin assignments before substitution, as packaging differences may exist between NLT and non-NLT suffixes.
