H2002DG

Overview

The H2002DG is a dual LAN pulse transformer designed for 10/100 Base-T Ethernet applications. It features a through-hole mounting configuration and supports a center tap to center tap (1CT:1CT) winding arrangement. The component provides an inductance of 350µH, ensuring signal integrity for data transmission networks.

Feature Summary

• Supports dual port connectivity for simultaneous network interface operations
• Engineered specifically for 10/100 Base-T Ethernet protocol compliance
• Utilizes a through-hole package design for robust mechanical integration

Applications

• Ethernet network interface cards
• Computer motherboard LAN ports
• Network switch hardware modules

Procurement Notes

Verify the specific manufacturer designation as Mentech Technology USA Inc. or Dongguan Mentech Optical & Magnetic Co., Ltd. when sourcing. Confirm that the component matches the 1CT:1CT specification and 350µH inductance requirement. Ensure the through-hole package type aligns with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component for designs requiring isolated signal coupling in standard Ethernet physical layers. The dual-port architecture simplifies board space requirements compared to single-port alternatives. Verify compatibility with the target network controller's electrical specifications to ensure proper impedance matching and signal performance.

Part Context

This part belongs to the category of pulse transformers used in telecommunications. It serves as a critical passive component for galvanic isolation and voltage level translation in wired networking equipment. The device facilitates reliable data transfer between the PHY chip and the external network medium.

Replacement Considerations

The H2001DG is a documented substitute offering similar dual LAN functionality. Both components support 10/100 Base-T standards. Verify pinout compatibility and mechanical dimensions before swapping to ensure seamless integration into existing assemblies.
