GMG116S1202R

Overview

The GMG116S1202R is a surface-mount audio and signal transformer manufactured by Amphenol Commercial Products. Designed for automotive applications, it supports 10/100 Base-T LAN connectivity with a 1:1 isolation ratio. The component features a 16-pin configuration and an inductance of 350 µH. It operates within a temperature range of -40°C to +125°C and utilizes SMD/SMT termination styles.

Feature Summary

• Supports 10/100 Base-T Ethernet magnetic coupling
• Automotive-grade thermal stability
• Surface-mount 16-pin package design

Applications

• Automotive Ethernet network interfaces
• 10/100 Base-T physical layer circuits
• Signal isolation in vehicle communication systems

Procurement Notes

Verify the specific manufacturer designation, as Amphenol ICC and Amphenol Commercial Products are distinct entities. Confirm the exact datasheet version matches the required automotive standards. Ensure the 16-pin SMD footprint aligns with the PCB layout before ordering. Check current availability status as distribution channels may vary.

Selection Notes

Select this component when automotive-rated isolation transformers are required for 10/100 Mbps Ethernet links. The high operating temperature limit suits under-hood or harsh environment installations. Verify that the 350 µH inductance meets the specific PHY requirements of the target network controller.

Part Context

This part belongs to the family of magnetic components used in Ethernet transceivers. It provides galvanic isolation between the MAC and the physical medium. The 16-pin form factor allows for compact integration into dense automotive electronic control units compared to larger through-hole alternatives.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 16-pin SMD footprint, 350 µH inductance, and automotive temperature rating with other manufacturers' automotive Ethernet transformer portfolios.
