RD8147-50-0M3

Overview

The Schaffner RD8147-50-0M3 is a current-compensated common mode choke designed for PCB mounting with wire termination. It features four channels and an inductance of 300 µH per path, with a tolerance of -30% to +50%. The component supports a maximum DC current of 50 A and has a typical DC resistance of 1.75 mΩ. It operates within a temperature range of -25°C to +110°C.

Feature Summary

• Current-compensated design for efficient magnetic field cancellation
• Four-channel configuration for multi-phase applications
• Wire termination style for robust PCB integration

Applications

• Power line filtering in industrial equipment
• EMI suppression in medical devices
• Electromagnetic compatibility enhancement in power supplies

Procurement Notes

Verify the specific datasheet version for the RD8147-50-0M3 to confirm exact mechanical dimensions and electrical tolerances. Ensure that the wire gauge and termination requirements match your PCB layout constraints. Cross-reference the manufacturer's official documentation for any updates on RoHS compliance or material declarations before finalizing procurement.

Selection Notes

Select this component when high current handling up to 50 A is required alongside significant common mode noise attenuation. The 300 µH inductance provides effective filtering at standard test frequencies. Consider the unshielded nature and physical footprint when designing for dense PCB layouts or environments sensitive to stray magnetic fields.

Part Context

This part belongs to the RD series of common mode chokes from TE Connectivity / Schaffner. These components are engineered for high-current applications requiring reliable EMI suppression. The RD series typically utilizes ferrite cores and is designed for through-hole mounting, offering a balance between performance and cost-effectiveness for industrial and medical power systems.

Replacement Considerations

Check for direct substitutes within the RD series with matching inductance and current ratings. Verify that alternative parts maintain the same channel count and termination style to ensure mechanical compatibility.
