RD6137-10-4M5

Overview

The Schaffner RD6137-10-4M5 is a three-phase current-compensated common mode choke designed for electromagnetic interference suppression. It features an inductance of 4.5 mH with a tolerance range of -25% to +110%. The component supports a maximum DC current of 10 A and exhibits a minimum DC resistance of 18.35 mOhms per phase. Rated for 600 VAC, it operates within a temperature range of -25°C to +110°C. The unit utilizes a toroidal ferrite core and employs wire termination for through-hole mounting.

Feature Summary

• Provides effective radio frequency interference suppression in three-phase power lines
• Utilizes current-compensated design to minimize magnetic field leakage
• Constructed with toroidal ferrite core for high efficiency and compact form factor

Applications

• Phase-angle control circuits
• CAT scanners
• Defibrillators
• X-ray equipment

Procurement Notes

Verify the specific inductance tolerance requirements against the datasheet, as the RD series allows for wide variance (-25% to +110%). Confirm that the 10 A current rating aligns with the peak load conditions of the target application. Ensure the through-hole wire termination method is compatible with the assembly process. Check RoHS compliance status if restricted substances are a constraint for the final product.

Selection Notes

Select this component when three-phase EMI filtering is required for medical or industrial imaging systems. The 4.5 mH inductance offers a balance between attenuation and physical size. Consider the 600 VAC rating for standard industrial voltage levels. The toroidal shape aids in reducing external magnetic fields, which is critical in sensitive diagnostic environments like MRI or CT suites where stray fields must be minimized.

Part Context

This part belongs to the Schaffner RD series of discrete chokes, specifically engineered for RFI suppression. The RD series is widely recognized in the EMC/EMI components market for providing optimized circuitry solutions. These components are typically used in conjunction with other filter elements to meet stringent electromagnetic compatibility standards in high-noise environments.

Replacement Considerations

Cross-reference with other Schaffner RD series models such as RD6137-16-1M5 for different current ratings. Verify that any substitute maintains the same three-phase configuration and toroidal form factor to ensure mechanical fit.
