RD8147-16-3M0

Overview

The Schaffner RD8147-16-3M0 is a four-line common mode choke designed for power line filtering. It features an inductance of 3 mH at 400 Hz with a tolerance range of -30% to +50%. The component supports a maximum DC current of 16 A and has a typical DC resistance of 9.25 mOhms. It operates within a temperature range of -25°C to +110°C and utilizes wire termination for PCB mounting.

Feature Summary

• Provides attenuation for common-mode or asymmetric interference signals when connected in series with the phase
• Designed specifically for use in phase-angle control circuits

Applications

• Phase-angle control circuits
• Power line EMI filtering
• Common-mode noise suppression in industrial electronics

Procurement Notes

Verify the specific part number suffix against official Schaffner documentation to ensure correct inductance and current ratings. Confirm that the 3 mH value corresponds to the 400 Hz test frequency specified in the datasheet. Ensure compatibility with the required 16 A current handling and 9.25 mOhm resistance limits for your circuit design before procurement.

Selection Notes

Select this component for applications requiring robust common-mode noise reduction in phase-controlled environments. The 4-line configuration allows for comprehensive filtering across multiple phases. Consider the thermal operating range up to 110°C and the physical mounting requirements for through-hole installation when integrating into the system layout.
