RP187-3-4.7-QD

Overview

The RP187-3-4.7-QD is a single-phase, dual-stage power line filter from the Astrodyne TDI RP187 series. It features an IEC inlet connector and quick connect terminals for panel or chassis mounting. Rated for 250 VAC at 3 A with a capacitance of 4.7 nF, it operates at 50/60 Hz. The unit has a leakage current of 800 uA and dimensions of approximately 17 mm height.

Feature Summary

• Dual-stage EMC/EMI suppression architecture
• Integrated IEC inlet connector design
• Quick connect terminal interface

Applications

• General-purpose electromagnetic interference suppression
• Single-phase AC power line filtering
• Equipment requiring IEC inlet connectivity

Procurement Notes

Verify the specific datasheet version for the RP187-3-4.7-QD to confirm exact dimensional tolerances and compliance certifications such as UL or CSA. Ensure the application voltage and current requirements align with the 250 VAC and 3 A ratings before procurement.

Selection Notes

Select this component when a compact, dual-stage filter with an integrated IEC inlet is required for 3 A applications. Compare against the RP188 series if single-stage performance suffices, or the RP187-6 variant if higher current capacity is needed.

Part Context

This model belongs to the RP187 series of high-performance dual-stage filters. It shares the series form factor but differs from the RP188 series in stage count and from other RP187 variants in current rating and capacitance values.

Replacement Considerations

The RP187-6-4.7-QD offers similar filtering characteristics but supports 6 A. Verify terminal compatibility and mounting constraints when substituting.
