RP225-20-2.2-QD

Overview

The Astrodyne TDI RP225-20-2.2-QD is a high-performance, dual-stage power line filter designed for single-phase applications. It features a 20 A current rating and a 250 VAC voltage rating, operating at standard frequencies of 50 Hz and 60 Hz. The unit utilizes quick connect terminals for electrical termination and supports chassis mounting. Key specifications include a capacitance of 2.2 nF and a leakage current range of 0 to 1.8 mA. The component measures 120.75 mm in length, 38 mm in height, and complies with UL, CSA, and EN standards.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• Chassis mount design with quick connect terminal interface
• Compliance with major international safety certifications

Applications

• Industrial machinery power conditioning
• Medical equipment EMI suppression
• Test and measurement instrument protection

Procurement Notes

Verify the specific datasheet version for the RP225-20-2.2-QD to confirm exact dimensional tolerances and certification marks prior to integration. Ensure that the quick connect terminal specifications match the mating connector requirements of the target system. Confirm compliance with relevant regional regulatory standards applicable to the final product deployment.

Selection Notes

Select this model when high attenuation performance is required for single-phase AC lines carrying up to 20 A. The dual-stage design distinguishes it from single-stage alternatives like the RP115 series. Verify that the chassis mounting style and physical dimensions fit the available enclosure space. Compare leakage current limits against sensitive application requirements if necessary.

Part Context

This component belongs to the RP225 series of high-performance power line filters from Astrodyne TDI. The series is characterized by dual-stage filtering capabilities and robust construction suitable for demanding environments. It shares the same form factor and mounting style as other variants in the series, such as the RP225-20-3.3-QD, differing primarily in capacitance values.

Replacement Considerations

The RP225-20-3.3-QD serves as a direct functional substitute within the same series, offering identical mechanical and electrical ratings except for a higher capacitance value of 3.3 nF versus 2.2 nF.
