H6501NL

Common Mode Chokes Overview

The H6501NL is a surface-mount common mode choke manufactured by Pulse Electronics. It features four lines and an inductance of 30 uH with a current rating of 0.8 A. The component has a maximum DC resistance of 200 mOhms and operates within a temperature range of -40°C to +85°C. It utilizes a non-polarized base (NPB) construction and is packaged in tubes for SMD mounting.

Common Mode Chokes Feature Summary

• Designed for Power over Ethernet (PoE) applications
• Surface mount technology for automated assembly
• Four-line configuration for multi-pair signal filtering

Common Mode Chokes Applications

• Power over Ethernet (PoE) circuit protection
• Common mode noise suppression in data lines
• Signal integrity enhancement in network interfaces

Common Mode Chokes Procurement Notes

Verify the specific suffix against official datasheets, as variations may exist between tube and reel packaging formats. Confirm RoHS compliance status directly from the manufacturer's documentation prior to integration. Ensure the selected variant matches the required inductance and current specifications for the target PoE application.

Common Mode Chokes Selection Notes

Select this component for designs requiring compact, four-line common mode filtering in PoE systems. Evaluate the 0.8 A current rating against peak load requirements. Consider the 200 mOhm DCR impact on power loss. Verify that the surface-mount footprint aligns with the PCB layout constraints.

Common Mode Chokes Part Context

This part belongs to Pulse Electronics' H6501 series of common mode chokes. The series offers various inductance values and line configurations tailored for Ethernet and PoE standards. The H6501NL specifically addresses the need for compact filtering solutions in space-constrained network hardware.

Common Mode Chokes Replacement Considerations

Check for H6501NLT if reel packaging is preferred over tubes. Verify equivalent parts from other manufacturers only if they match the 30 uH inductance, 0.8 A rating, and four-line SMD form factor.
