H0022NLT

Overview

The H0022NLT is a surface-mount LAN transformer module manufactured by Pulse Electronics. Designed for 10/100Base-TX applications, this single-port unit operates without Power over Ethernet (PoE) support. It features an integrated common mode choke and isolation transformer within a compact SMD package. The component provides electrical isolation with a rated insulation voltage of 1500 Vrms. Key electrical specifications include a primary DC resistance of 1 Ohm and a secondary DC resistance of 0.3 Ohms. The module supports data transmission frequencies up to 100 MHz and is suitable for commercial temperature ranges.

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact pinout configuration and mechanical dimensions. Ensure compatibility with target PCB footprint and soldering thermal profiles. Confirm that the selected variant meets all required regulatory standards for the intended end-use market. Cross-reference datasheet revision history for any recent design changes affecting performance or form factor.

Selection Notes

Select this component for designs requiring standard 10/100 Mbps Ethernet isolation without PoE power delivery requirements. Consider the single-port architecture for cost-sensitive applications where dual-port functionality is unnecessary. Evaluate the surface-mount package size constraints against available board space. Verify that the insulation voltage rating aligns with safety requirements for the specific application environment.
