RP120-20-4.7-QD

Overview

The Astrodyne TDI RP120-20-4.7-QD is a medium-high performance, single-stage power line filter designed for 1-phase applications. It features a 250 VAC voltage rating and a 20 A current capacity. The unit utilizes quick connect terminals for electrical termination and supports chassis mounting. Key specifications include a capacitance of 4.7 nF, a leakage current of 800 uA, and operation at 50 Hz or 60 Hz frequencies. It holds UL, CSA, and EN compliance certifications.

Feature Summary

• Single-stage filtering architecture for general-purpose noise suppression
• Chassis mount design with quick connect terminal interface
• Certified to UL, CSA, and EN safety standards

Applications

• General purpose electronic equipment power conditioning
• Industrial control systems requiring 1-phase filtration
• Medical device power input stages

Procurement Notes

Verify the specific datasheet version for the RP120-20-4.7-QD to confirm exact dimensional tolerances and terminal spacing before integration. Ensure that the installation environment remains within the specified operating temperature range to maintain certification validity. Cross-reference the 4.7 nF capacitance value against system leakage current limits to ensure regulatory compliance in the final assembly.

Selection Notes

Select this component when a single-stage solution is sufficient for EMI reduction in 1-phase circuits. The 20 A rating accommodates moderate load requirements without necessitating a dual-stage topology. Verify that the chassis mounting style aligns with the available panel space and that quick connect terminals are compatible with the wiring harness configuration.

Part Context

This model belongs to the RP120 series, which offers medium-high performance filtering capabilities. The series provides various current ratings and capacitance options to suit different power line requirements while maintaining a consistent form factor and mounting style for standardized integration into power supply inputs.

Replacement Considerations

Direct substitutes within the same series include the RP120-10-4.7-QD for lower current needs or the RP120-30-4.7-QD for higher capacity. Ensure any replacement maintains the 4.7 nF capacitance and quick connect terminal type to preserve mechanical and electrical compatibility.
