Overview
The H0019NLT is a surface-mount LAN transformer module manufactured by Pulse Electronics, designed for 10/100Base-TX Ethernet applications. It features a single-port configuration with SMD/SMT termination and operates within a frequency range of 1 MHz to 100 MHz. The component provides galvanic isolation between network lines and includes an integrated 1 Ohm common mode choke. Key electrical specifications include an inductance of 350 uH and an insulation voltage rating of 1.5 kV. The module supports an operating temperature range from -40°C to +85°C and has physical dimensions of approximately 27.8 mm in length, 15.2 mm in width, and 7.2 mm in height.
Feature Summary
- Provides galvanic isolation for 10/100 Mbps Ethernet data transmission
- Integrates a 1 Ohm common mode choke for noise suppression
- Supports high-temperature operation up to 85°C
Applications
- 10/100Base-TX Ethernet network interfaces
- PCMCIA network cards
- Industrial communication equipment requiring robust isolation
Procurement Notes
Verify the specific datasheet version and RoHS compliance status before procurement, as manufacturing updates may occur. Confirm that the surface-mount package dimensions align with your PCB footprint requirements. Ensure that the thermal management strategy accounts for the specified operating temperature range during integration into the final assembly process.
Selection Notes
Select this component when designing for 10/100Base-TX standards requiring integrated common mode filtering. It is suitable for space-constrained applications due to its compact SMD form factor. Consider the 1.5 kV insulation rating for safety isolation needs. Verify compatibility with automated pick-and-place processes given the reel packaging format.
Part Context
This part belongs to Pulse Electronics' LAN transformer portfolio, specifically tailored for legacy Fast Ethernet implementations. It serves as a critical interface component between the PHY transceiver and the external network medium, ensuring signal integrity and electrical safety through magnetic isolation.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official manufacturer cross-reference guides for potential alternatives.
