RD8127-50-1M0

Overview

The Schaffner RD8127-50-1M0 is a current-compensated common mode choke designed for power line filtering. It features an inductance of 1 mH per path with a maximum DC current rating of 50 A and a maximum DC resistance of 2.5 mohms. The component operates within a temperature range of -40°C to +125°C and utilizes nanocrystalline core material. It is constructed as an unshielded, horizontal mount device intended for robust electromagnetic interference suppression in industrial environments.

Feature Summary

• Current-compensated design for effective common mode noise attenuation
• Nanocrystalline core material for high magnetic performance
• Horizontal mounting configuration for space-efficient integration

Applications

• Industrial automation systems
• Power supply units
• Electromagnetic compatibility (EMC) filtering

Procurement Notes

Verify the specific manufacturer part number against official TE Connectivity or Schaffner documentation to ensure authenticity. Confirm that the nanocrystalline core specifications and current ratings match the application requirements. Check for any recent product change notices regarding packaging or material composition before finalizing procurement orders.

Selection Notes

Select this component when high current handling capability up to 50 A is required alongside significant common mode inductance. The nanocrystalline core offers superior saturation characteristics compared to traditional ferrite cores. Ensure the horizontal mounting style aligns with the mechanical constraints of the target PCB or chassis assembly.

Part Context

This component belongs to the RD series of current-compensated chokes from Schaffner EMC Inc., now part of TE Connectivity. The series is engineered for demanding power electronics applications where compact size and high efficiency are critical. It complements other Schaffner filters by providing robust passive filtering solutions for mid-to-high power ranges.

Replacement Considerations

Consult official datasheets for direct cross-references. Verify electrical parameters such as inductance tolerance and DC resistance when evaluating alternative parts.
