RD7147-6-6M0

Overview

The Schaffner RD7147-6-6M0 is a path current-compensated common mode filter belonging to the RD series. It features four channels with a nominal inductance of 6 mH and a tolerance range of -30% to +50%. The component supports a maximum DC current of 6 A and exhibits a maximum DC resistance of 45.1 mohms. Designed for through-hole wire termination, it operates within a temperature range of -25°C to +125°C. The physical dimensions are 70 mm x 70 mm x 40 mm.

Feature Summary

• Path current-compensated design for balanced noise suppression
• Four-channel configuration for multi-phase applications
• Through-hole wire termination for robust mechanical mounting

Applications

• Industrial power supply input filtering
• Motor drive EMC mitigation
• Uninterruptible power system (UPS) noise reduction

Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributor, as documentation indicates detailed but unspecified compliance data. Confirm that the specific order suffix matches the required inductance tolerance and current rating specifications for your circuit design before finalizing procurement.

Selection Notes

Select this component when high current handling up to 6 A is required alongside significant common mode attenuation. Ensure the PCB layout accommodates the 70x70x40 mm footprint and allows sufficient clearance for wire terminations. Validate thermal management capabilities given the operating temperature limit of 125°C under full load conditions.

Part Context

This component is part of the Schaffner RD series, now integrated into TE Connectivity's portfolio following the acquisition of Schaffner. The series specializes in electromagnetic compatibility solutions, providing standardized and bespoke components for power quality improvement and interference suppression in demanding electronic environments.

Replacement Considerations

Consult official substitution guides for equivalent RD series variants with adjusted inductance values. Verify pin compatibility and thermal characteristics against alternative manufacturers' common mode chokes rated for similar current levels.
