LG2P109RN LF

Overview

The LG2P109RN LF is a LAN 1000 Base-T pulse transformer manufactured by Pulse Electronics. It features a 350µH inductance and a 1:1CT turns ratio for both transmitter and receiver ports. Designed for through-hole mounting, the component measures 32.50mm in length, 8.50mm in width, and has a maximum height of 11.60mm. It operates within a temperature range of 0°C to 70°C and complies with RoHS3 standards.

Feature Summary

• Dual port configuration supporting 1000 Base-T LAN applications
• Integrated common mode choke functionality with specified inductance
• Through-hole package design for standard PCB assembly

Applications

• Gigabit Ethernet network interface cards
• LAN transceiver modules
• Network switch hardware

Procurement Notes

Verify the specific suffix 'RN' against the official datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the component meets the required thermal operating range of 0°C to 70°C for the target environment. Confirm RoHS3 compliance status if restricted substances are a constraint for the final assembly.

Selection Notes

Select this component when a dual-port Gigabit Ethernet magnetic solution is required with through-hole compatibility. The 350µH inductance value must align with the PHY chip specifications. Consider the physical dimensions of 32.50mm x 8.50mm x 11.60mm for board space constraints compared to surface mount alternatives.

Part Context

This part belongs to the Pulse Electronics LAN transformer family designed for high-speed data transmission. It serves as a critical isolation component in Ethernet interfaces, providing signal coupling and impedance matching between the MAC controller and the physical medium connector.

Replacement Considerations

LG2P109N LF is listed as a parameter equivalent substitute by the manufacturer.
