G2PM109RN LF

Overview

The G2PM109RN LF is a LAN 1000 Base-T pulse transformer manufactured by Pulse Electronics. It features a dual-port configuration with 1:1CT turns ratio for both transmitter and receiver channels. The component utilizes a 48-pin DIP through-hole package, measuring 32.50mm in length, 8.50mm in width, and 11.60mm in height. Key electrical specifications include an inductance of 350µH and isolation voltage of 1500Vrms. It operates within a temperature range of 0°C to 70°C and complies with RoHS3 standards.

Feature Summary

• Designed for Ethernet 100/1000 BASE-T full duplex applications
• Supports eight pairs of Category 5 UTP cable interfaces
• Provides galvanic isolation between network lines

Applications

• Ethernet 100/1000 BASE-T full duplex network interfaces
• Category 5 UTP cable connectivity systems
• LAN port signal transmission and reception modules

Procurement Notes

Verify the specific suffix variant against the design schematic, as sub-variants like G2PM109RNS2 LF exist with identical core functions but potential packaging differences. Confirm that the 48-pin DIP form factor matches the PCB footprint requirements. Ensure compliance with RoHS3 regulations is documented for the specific batch. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for designs requiring dual-port Gigabit Ethernet isolation with through-hole mounting constraints. The 350µH inductance value must align with the PHY transceiver specifications. Consider the physical dimensions of the 48-pin DIP package when planning board layout clearance. Verify thermal performance within the 0°C to 70°C operating range for the intended environment.

Part Context

This component belongs to the Pulse Electronics LAN 1000 Base-T transformer family. It serves as a magnetics module for network interface cards and switches. The product line emphasizes signal integrity and isolation for high-speed data transmission over twisted pair cabling.
