E2023NL

Overview

The E2023NL is a surface-mount pulse transformer manufactured by Pulse Electronics, designed for LAN isolation and data interface applications. It supports 10BASE-T Ethernet standards with a turns ratio of 1CT:2.5CT for the transmitter and 1CT:1CT for the receiver. The component features an inductance of 200µH and operates within a temperature range of 0°C to 70°C. Its physical dimensions are 12.57mm in length, 7.11mm in width, and 5.33mm in maximum height. The unit utilizes gull-wing SMD termination and is packaged in tubes.

Feature Summary

• Provides galvanic isolation for 10BASE-T network interfaces
• Encapsulated construction for data integrity
• Surface mount design for automated assembly

Applications

• 10BASE-T Ethernet port implementation
• LAN isolation circuits
• Data interface modules requiring signal transformation

Procurement Notes

Verify that the specific order suffix matches the required packaging configuration, as standard supply may utilize tube packaging. Confirm compliance with RoHS3 specifications and REACH status prior to integration. Ensure the procurement channel sources genuine components from authorized distributors to guarantee electrical performance and reliability standards are met.

Selection Notes

Select this component for designs requiring non-PoE 10BASE-T isolation with specific impedance matching. The 1CT:2.5CT and 1CT:1CT winding configurations dictate compatibility with specific PHY transceiver architectures. Verify footprint constraints against the 12.57mm x 7.11mm outline and ensure thermal management aligns with the 70°C operational limit.

Part Context

This part belongs to the Pulse Electronics audio and signal transformer portfolio, specifically categorized under LAN transformers. It serves as a passive magnetic component essential for maintaining signal integrity and electrical safety in legacy 10Mbps Ethernet networks. The encapsulated design distinguishes it from open-wound variants, offering enhanced environmental protection.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires identical electrical parameters including 200µH inductance, 1CT:2.5CT/1CT:1CT ratios, and compatible SMD package dimensions.
