Overview
The H5019EFNLT is a LAN pulse transformer manufactured by Pulse Electronics, designed for 10/100/1000 Base-T applications. It features a turns ratio of 1CT:1 for both transmitter and receiver channels. The component has an inductance of 350µH and operates within a temperature range of 0°C to 70°C. It utilizes a surface-mount package with dimensions of 19.81mm x 19.05mm x 2.54mm maximum height. The device is RoHS3 compliant and classified under ECCN EAR99.
Feature Summary
- Supports Gigabit Ethernet (10/100/1000 Base-T) transmission standards
- Integrated single-port design with separate transmitter and receiver windings
- Surface-mount construction for automated assembly integration
Applications
- Gigabit Ethernet network interface cards
- Ethernet switch port circuits
- Network adapter hardware
Procurement Notes
Verify the specific suffix 'E' against official manufacturer documentation to confirm exact variant specifications, as ordering suffixes may indicate distinct functional or environmental parameters. Cross-reference the DigiKey part number 553-2232-2-ND for accurate distributor identification. Confirm current lifecycle status directly with Pulse Electronics, as availability data varies across sources.
Selection Notes
Select this component for designs requiring standard 10/100/1000 Base-T isolation with a 350µH primary inductance. Ensure the PCB footprint accommodates the 19.81mm x 19.05mm outline and 2.54mm maximum height. Verify that the operating temperature range of 0°C to 70°C meets the system's thermal requirements.
Part Context
This component belongs to the Pulse Electronics LAN transformer family, specifically engineered for high-speed data communication interfaces. It serves as a critical isolation element in Ethernet PHY circuits, providing signal coupling and impedance matching for reliable data transmission over twisted-pair cabling.
Replacement Considerations
HX5019FNLT is a similar active part from the same manufacturer with identical electrical characteristics but a wider operating temperature range (-40°C to 85°C). H5019FNLT is listed as discontinued. Verify pin compatibility and mechanical footprint before substitution.
