H1164T

Overview

The H1164T is a LAN signal transformer module designed for 100Base-TX applications. It features surface mount termination and provides four channels with an inductance of 350uH and primary impedance of 0.65 Ohms. The device supports an isolation voltage of 1.5 kV and operates within a temperature range of -40°C to +85°C. Dimensions are 28.58 mm length, 16.256 mm width, and 13.843 mm height.

Feature Summary

• Supports 100Base-TX Ethernet signaling standards
• Provides galvanic isolation via 1.5 kV insulation voltage
• Designed for non-PoE network interface applications

Applications

• 100Base-TX network interfaces
• Auto MDI/MDIX circuit implementations
• Ethernet port signal conditioning modules

Procurement Notes

Verify RoHS compliance status as documentation indicates variations between standard and versioned configurations. Confirm moisture sensitivity handling requirements due to declared MSL classification. Ensure the specific suffix matches the required operating temperature range and packaging format before ordering.

Selection Notes

Select this component for high-temperature environments requiring operation down to -40°C. The quad-channel design suits multi-port or complex single-port PHY solutions. Verify physical footprint compatibility against the 28.58mm x 16.256mm package dimensions during PCB layout planning.

Part Context

This part belongs to the Pulse Electronics LAN transformer series. It serves as a critical passive component for isolating network transceivers from external cabling. The module integrates magnetic components to ensure signal integrity and electrical safety in wired communication systems.

Replacement Considerations

The H1164NLT is a documented variant within the same family. Verify if the NLT suffix meets the specific thermal and packaging requirements of the target application.
