H2001DG

Overview

The H2001DG is a dual-port pulse transformer designed for 10/100 BASE-T Ethernet applications. It features a through-hole construction with a DIP20 package, facilitating integration into standard PCB layouts. The component provides electrical isolation and signal coupling for LAN networks, supporting data transmission speeds of 10 Mbps and 100 Mbps. It incorporates a primary inductance specification of 350µH to ensure effective impedance matching and signal integrity within the network interface circuitry.

Feature Summary

• Dual-port configuration for simultaneous network channel processing
• Through-hole mounting design compatible with DIP20 footprints
• Optimized for 10/100 BASE-T Ethernet signal coupling

Applications

• Ethernet network interface cards (NICs)
• LAN hub and switch internal circuitry
• Computer motherboard network controllers

Procurement Notes

Verify the specific datasheet version from Mentech Technology USA Inc. to confirm pinout compatibility and insulation ratings. Ensure the DIP20 package dimensions align with the target PCB layout. Cross-reference the 350µH inductance requirement against the system's impedance matching specifications before finalizing the procurement order.

Selection Notes

Select this component when designing for 10/100 BASE-T standards requiring dual-channel isolation. The through-hole format is suitable for high-reliability industrial or legacy systems where surface-mount alternatives are not preferred. Confirm that the voltage isolation capabilities meet the safety requirements of the specific network environment.

Part Context

This part belongs to the Mentech LAN transformer series, which includes single and dual-port variants for various Ethernet speeds. The H2001DG specifically addresses dual-port needs for 10/100 Mbps networks, distinguishing it from single-port models like the G1801DG or higher-speed Gigabit variants.

Replacement Considerations

Direct substitutes may include other dual-port 10/100 BASE-T pulse transformers in DIP20 packages with comparable 350µH inductance. Verify pin-to-pin compatibility and electrical parameters before substitution.
