H2260FNLT

Overview

The H2260FNLT is a single-port LAN pulse transformer module manufactured by Pulse Electronics, designed for Surface Mount Device (SMD) integration. It supports 10/100 Base-T Ethernet standards with Power over Ethernet (PoE) capabilities. The component features an inductance of 350µH and a primary DC resistance of 0.65 Ohms. It operates within a frequency range of 1 MHz to 125 MHz and withstands an isolation voltage of 1.5 kV. The physical dimensions are 12.7 mm in length, 9.09 mm in width, and 5.99 mm in height. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Supports integrated Power over Ethernet (PoE) functionality for simultaneous data and power transmission
• Provides galvanic isolation via 1.5 kV insulation voltage rating
• Optimized for high-frequency signal integrity within the 1 MHz to 125 MHz bandwidth

Applications

• 10/100 Base-T network interface cards
• Ethernet switches and hubs with PoE support
• VoIP telephones requiring integrated power delivery

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact packaging configuration and RoHS compliance status. Ensure the procurement channel provides valid traceability for electronic components. Cross-reference the datasheet revision date to guarantee compatibility with current design specifications. Confirm that the received units match the specified SMD package dimensions and pinout requirements before assembly.

Selection Notes

Select this component when designing circuits requiring combined data signaling and power delivery over a single Ethernet port. The wide operating temperature range makes it suitable for industrial or outdoor applications. Verify that the board layout accommodates the specific footprint dimensions. Consider the 350µH inductance value for its impact on common mode rejection and signal filtering requirements in the target application.
