RP187-6-4.7-QD

Overview

The Astrodyne TDI RP187-6-4.7-QD is a single-phase, dual-stage power line filter designed for high-performance electromagnetic interference suppression. It features an IEC C14 inlet and utilizes quick-connect tabs for termination. The unit is rated for 250 VAC and supports a continuous current of 6 A at operating frequencies of 50 Hz or 60 Hz. Key electrical specifications include a capacitance value of 4.7 nF and a maximum leakage current of 800 uA. The component complies with UL, CSA, and EN standards.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• Integrated IEC C14 power inlet connector
• Quick-connect tab termination style for simplified assembly

Applications

• Industrial control systems requiring EMI/RFI suppression
• Medical equipment power inputs
• Test and measurement instrumentation

Procurement Notes

Verify the specific datasheet version to confirm compliance certifications such as UL, CSA, and EN before integration. Ensure that the chassis mounting dimensions and terminal spacing align with the mechanical design constraints of the target enclosure. Confirm that the 6 A current rating and 250 VAC voltage limit are sufficient for the operational requirements of the connected load.

Selection Notes

Select this model when a compact, dual-stage solution is required for single-phase AC lines up to 6 A. The integrated IEC inlet simplifies wiring compared to separate receptacle and filter combinations. Consider the 4.7 nF capacitance value in relation to allowable leakage current limits for sensitive applications. Verify that the quick-connect terminals match the available harness or PCB interface options.

Part Context

This component belongs to the RP187 series of high-performance power line filters from Astrodyne TDI. The series offers various current ratings including 1 A, 3 A, 6 A, 10 A, and 20 A. Variants are available with either quick-connect (QD) tabs or wire leads (W), allowing flexibility in connection methods while maintaining consistent dual-stage filtering performance across the product family.

Replacement Considerations

Direct substitutes within the same series include RP187-1-0-QD, RP187-3-4.7-QD, RP187-10-4.7-QD, and RP187-20-4.7-QD, which share identical form factors and electrical characteristics but differ in current ratings. Cross-series replacements require verification of mounting dimensions and terminal types.
