Features&Benefits

  • Dual-Port Integration: Combines two independent transformer channels in a single module, saving PCB space.
  • Signal Integrity: Provides essential functions including isolation, impedance matching, and noise suppression for stable Ethernet data transmission.
  • Robust Construction: Through-hole terminals ensure a strong, reliable connection to the PCB, resistant to mechanical stress.
  • Standards Compliance: Designed to meet IEEE 802.3 specifications for 10/100 Mbps Ethernet networks.

 

Packing Details

Specific packing details for TH12010D are not listed in the available documents. Our standard practice is to package components securely in trays or tubes for bulk handling. For exact quantities per package, please contact our sales team directly.

 

Applications

This transformer module is primarily used in the manufacturing of various networking and communication devices, such as:

  • Network Switches and Hubs
  • Routers and Gateways
  • Industrial Control and Automation Systems
  • Embedded Computing Boards with Ethernet functionality

 

Frequently Asked Questions (FAQ) 

  • Q: What is the main purpose of this LAN transformer module in an Ethernet circuit?
  • A: Its primary purposes are electrical isolation to protect sensitive chips from voltage surges, impedance matching between the PHY chip and the cable for optimal signal transfer, and suppression of common-mode noise to improve signal integrity and reduce EMI.
  • Q: Is the TH12010D compatible with Gigabit Ethernet (1000BASE-T)?
  • A: No. The TH12010D is specified for 10/100 Base-T networks, supporting speeds up to 100 Mbps. For Gigabit Ethernet applications, you would need a transformer module rated for 1000 Base-T standards.
  • Q: What are the advantages of choosing a through-hole (DIP) mount transformer like this one over a surface-mount (SMD) type?
  • A: The through-hole design provides superior mechanical strength and bond to the PCB, making it ideal for applications subject to vibration, physical stress, or where manual soldering/rework might be involved. SMD types are better for automated assembly and very high-density designs.
