RP105-20-1-QD

Overview

The RP105-20-1-QD is a compact, single-phase, single-stage power line filter manufactured by Astrodyne TDI. It features a chassis mount design with quick connect termination for straightforward integration. The unit is rated for 250 VAC and supports a continuous current of 20 A at operating frequencies of 50 Hz and 60 Hz. Key electrical specifications include a capacitance value of 4.7 nF and a leakage current range between 0 A and 1.57 mA. The component measures 51 mm in length and 29 mm in height, complying with UL, CSA, and EN standards.

Feature Summary

• Single-stage filtering architecture designed for general-purpose EMI/EMI suppression
• Compact physical footprint suitable for space-constrained chassis installations
• Quick connect terminal interface facilitates rapid assembly and maintenance

Applications

• Industrial machinery power input stages
• Medical equipment power conditioning
• General purpose electronic systems requiring 20A single-phase filtration

Procurement Notes

Verify the specific suffix QD confirms quick connect terminals against your schematic requirements. Ensure the chassis mounting hole pattern matches your enclosure design. Confirm that the 250 VAC rating aligns with your local mains voltage standards. Check that the 20 A current capacity exceeds your system's maximum load to prevent thermal issues. Validate compliance certifications such as UL or EN are accepted in your target market.

Selection Notes

Select this model when a single-stage solution meets your attenuation needs without requiring dual-stage complexity. The 20 A rating distinguishes it from lower-current variants in the RP105 series. Choose this part if quick connect wiring is preferred over stud or PCB mount options. Consider the 4.7 nF capacitance value for its impact on leakage current limits within your safety regulations.

Part Context

This component belongs to the RP105 series of power line filters from Astrodyne TDI. The series offers various current ratings and termination styles. The RP105 designation indicates a single-stage configuration. This specific model represents a mid-range current option within the compact form factor category.

Replacement Considerations

Direct substitutes may include other RP105-20-*-QD variants with different capacitance values. Cross-reference dimensions and mounting patterns before replacing. Verify that alternative parts maintain the same 20 A current rating and 250 VAC voltage limit.
