RP105-20-4.7-QD

Overview

The RP105-20-4.7-QD is a compact single-phase, single-stage power line filter manufactured by Astrodyne TDI. It features a voltage rating of 250 VAC and a current capacity of 20 A. The unit includes a capacitance value of 4.7 nF and supports operating frequencies of 50 Hz and 60 Hz. Physical dimensions are 51 mm in length and 29 mm in height. Leakage current ranges from 0 to 1.57 mA. The device utilizes quick connect termination and chassis mount installation style.

Feature Summary

• Compact single-stage design for efficient space utilization
• Quick connect termination for simplified wiring integration
• Chassis mount configuration for secure mechanical attachment

Applications

• Single-phase AC power line filtering
• EMI/RFI suppression in electronic equipment
• Compliance with electromagnetic interference standards

Procurement Notes

Verify the specific suffix QD corresponds to the quick disconnect terminal type required for your assembly. Confirm that the 20 A current rating and 250 VAC voltage limit align with your system's operational parameters. Ensure chassis mounting provisions match the physical footprint of 51 mm by 29 mm. Check compliance certifications such as UL, CSA, and EN against regional regulatory requirements before finalizing procurement.

Selection Notes

Select this component when a low-profile, single-phase filter is needed for currents up to 20 A. The quick connect interface suits applications requiring rapid assembly or maintenance access. Consider the 4.7 nF capacitance for standard EMI attenuation needs. Verify thermal limits, as the maximum operating temperature is specified at +40 C. Ensure the leakage current specification meets safety isolation requirements for the target application.

Part Context

This model belongs to the RP105 series of power line filters from Astrodyne TDI. The series focuses on compact form factors suitable for space-constrained installations. The RP105 designation indicates a single-phase architecture. The numerical values in the part number denote current rating and capacitance characteristics. This series is designed for general industrial and commercial electronic applications requiring basic EMI suppression.

Replacement Considerations

Direct substitutes within the same series include models with similar current ratings but different capacitance values, such as RP105-20-10-QD. Cross-series replacements like the RP135 series offer higher performance but differ in size and cost. Verify terminal type compatibility when substituting, as QD denotes quick disconnect connections. Ensure replacement parts maintain equivalent voltage and current ratings.
