EX2024NL

Overview

The EX2024NL is a surface-mount LAN isolation transformer manufactured by Pulse Electronics, designed for 10Base-T applications. It features an inductance of 350µH and supports a turns ratio of 1CT:2.5CT for the transmitter and 1CT:1CT for the receiver. The component operates within a temperature range of -40°C to +85°C and provides 2 kV insulation voltage. Its physical dimensions are 12.7 mm in length, 7.24 mm in width, and 5.08 mm in height, with a maximum DC resistance of 600 mOhms.

Feature Summary

• Provides galvanic isolation for 10Base-T Ethernet signals
• Supports integrated data interface functionality
• Designed for surface-mount technology (SMD) assembly

Applications

• 10 Base-T network interfaces
• LAN isolation circuits
• Data communication equipment

Procurement Notes

Verify the specific package variant upon ordering, as distributor listings may reference both tube and tape-and-reel configurations for this part number. Confirm that the required inductance value aligns with the design specifications, noting potential discrepancies between datasheet values and marketplace descriptions. Ensure compatibility with the target operating temperature range before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring 10Base-T isolation with specific 350µH inductance requirements. Verify that the SMD footprint matches the PCB layout constraints. Consider the thermal performance limits when evaluating placement near heat-generating components. Ensure the insulation voltage rating meets the safety isolation requirements of the system architecture.

Part Context

This component belongs to the EX2024 series of LAN transformers from Pulse Electronics. It serves as a specialized magnetic component for Ethernet connectivity, distinct from higher-speed variants like those supporting PoE or Gigabit standards. The series focuses on basic 10 Mbps transmission needs with compact surface-mount packaging.

Replacement Considerations

The EX2024NL is parameter-equivalent to the EX2024NL (non-LT suffix). Verify mechanical and electrical compatibility before substitution.
