RP120-20-4.7-S

Overview

The Astrodyne TDI RP120-20-4.7-S is a single-phase, single-stage power line filter designed for chassis mounting. It features a rated voltage of 250 VAC and a current rating of 20 A at operating frequencies of 50 Hz and 60 Hz. The component utilizes quick connect terminals with an M4 threaded post interface. Key electrical specifications include a capacitance of 4.7 nF and a maximum leakage current of 800 uA. The unit complies with UL, CSA, and EN standards.

Feature Summary

• Single-stage EMI/EMI filtering architecture
• Chassis mount installation style
• Quick connect terminal interface

Applications

• Industrial equipment power conditioning
• Medical device power supplies
• Commercial machinery EMC compliance

Procurement Notes

Verify the specific datasheet version to confirm exact dimensional tolerances and terminal spacing before integration. Ensure the mounting surface supports the required thermal dissipation characteristics. Confirm that the 20 A continuous current rating aligns with the system's peak load requirements without derating issues.

Selection Notes

Select this model when a single-stage solution is sufficient for the required attenuation levels. The 20 A rating suits moderate power applications where space constraints favor a compact chassis-mount design. Verify that the 4.7 nF capacitance value meets the specific leakage current limits mandated by the target application's safety regulations.

Part Context

This component belongs to the RP120 series, which offers medium-high performance filtering capabilities. The series provides various current ratings and termination options to accommodate different power distribution needs within single-phase AC systems.

Replacement Considerations

Cross-reference with other RP120 variants if current or capacitance values differ from system requirements. Ensure substitute parts maintain compatible mounting dimensions and terminal types to avoid mechanical redesign.
