Overview
The H5019FNL is a single-channel LAN pulse transformer module designed for 10/100/1000 Base-T applications. It features a 350 µH inductance and a 1CT:1 turns ratio for both transmitter and receiver circuits. The component supports surface mount technology with dimensions of 19.81 mm length, 19.05 mm width, and 2.54 mm height. It operates within a temperature range of 0°C to +70°C and provides 1.5 kV isolation voltage. The unit is unshielded and complies with RoHS standards.
Feature Summary
- Supports 10/100/1000 Base-T Ethernet signaling
- Provides galvanic isolation between circuit sections
- Designed for surface mount assembly processes
Applications
- PCMCIA network interface cards
- Single-port non-PoE Ethernet hubs
- LAN adapter modules
Procurement Notes
Verify the specific suffix configuration when ordering, as adding a 'T' changes the packaging to tape and reel. Confirm that the standard tube packaging aligns with your automated placement equipment requirements. Ensure the selected variant matches the required thermal operating range for your specific design environment.
Selection Notes
Select this component for designs requiring a single-channel solution without Power over Ethernet capabilities. The unshielded construction may require careful layout considerations regarding electromagnetic interference. Verify that the 0°C to +70°C operating range meets the environmental specifications of the target application before integration.
Part Context
This part belongs to the Pulse Electronics LAN transformer family, which includes variants like HX5019FNL for extended temperature ranges. It serves as a signal conditioning component for copper-based Ethernet physical layer interfaces. The module integrates primary and secondary windings to facilitate data transmission across twisted-pair cabling.
Replacement Considerations
HX5019FNL offers an equivalent electrical specification with an extended industrial temperature range. H5015FNL provides a two-channel configuration suitable for different port count requirements.
