RP187-20-.47-QD

Overview

The Astrodyne TDI RP187-20-.47-QD is a high-performance dual-stage power line filter designed for single-phase applications. It features an IEC inlet connector with quick disconnect terminals and operates at a rated voltage of 250 VAC and a current rating of 20 A. The unit incorporates a 470 pF capacitance value and maintains a leakage current of 80 uA. Designed for panel mounting, it supports operating frequencies of 50 Hz and 60 Hz. The component holds cURus and EN60939 compliance certifications.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• Integrated IEC inlet with male quick disconnect terminals
• High-performance design optimized for electromagnetic interference suppression

Applications

• Single-phase electronic equipment requiring EMI/RFI suppression
• Medical devices adhering to strict leakage current standards
• Industrial control systems utilizing IEC inlet connections

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure terminal type and capacitance values match system requirements. Confirm that the 20 A current rating and 250 VAC voltage specifications align with the target application's electrical parameters. Check for regional distribution availability as supply status may vary by location.

Selection Notes

Select this model when dual-stage attenuation is required within a compact form factor. Ensure the chassis or panel allows for the specified mounting style. Verify that the 80 uA leakage current meets safety isolation requirements for the intended environment. Confirm compatibility with the mating IEC inlet connector on the equipment side.

Part Context

This component belongs to the RP187 series from Astrodyne TDI, which specializes in high-performance power line filters. The series typically offers dual-stage filtering solutions for single-phase AC lines. These filters are engineered to provide superior common-mode and differential-mode noise rejection compared to standard single-stage units.

Replacement Considerations

Direct substitutes include the RP187-10-.47-QD for lower current applications and the RP187-20-4.7-QD for higher capacitance needs. Verify that any replacement maintains the same dual-stage topology and quick disconnect terminal configuration.
