HX5019FNL

Overview

The HX5019FNL is a single-channel LAN transformer module from Pulse Electronics, designed for 1000Base-T PCMCIA applications without Power over Ethernet. It features surface mount termination and operates within a frequency range of 100 kHz to 125 MHz. The component provides an inductance of 350 uH and supports an isolation voltage of 1.5 kV. Physical dimensions are 19.81 mm in length, 19.05 mm in width, and 2.54 mm in height. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Supports 1000Base-T PCMCIA network interfaces
• Provides electrical isolation via 1.5 kV insulation voltage
• Designed for non-PoE signal transmission
• Operates effectively across extended industrial temperature ranges

Applications

• 1000Base-T PCMCIA network cards
• Single-port LAN interface modules
• Non-PoE data communication equipment

Procurement Notes

Verify the specific suffix 'FNL' corresponds to tube packaging rather than tape and reel variants like 'FNLT'. Confirm RoHS compliance status through official documentation. Ensure the application requires non-PoE specifications, as this model does not support power delivery. Cross-reference datasheet revision dates to validate current manufacturing parameters.

Selection Notes

Select this component for space-constrained PCMCIA form factors requiring Gigabit Ethernet connectivity. The unshielded design suits applications where external shielding is managed by the chassis. Verify that the 350 uH inductance meets the specific PHY requirements of the target network controller. Consider thermal management capabilities given the wide operating temperature range.

Part Context

This part belongs to the HX series of LAN transformers from Pulse Electronics. It is distinct from similar models like H5015FNL or HX5019FNLT primarily by its packaging format and specific PCMCIA orientation. The FNL suffix typically indicates tube packaging, differentiating it from reel-based alternatives.

Replacement Considerations

HX5019FNLT serves as a functional equivalent with identical electrical characteristics but utilizes tape and reel packaging instead of tubes. Designers must verify mechanical footprint compatibility when substituting between these variants.
