RP105-20-10-QD

Overview

The RP105-20-10-QD is a single-phase, single-stage power line filter module from the Astrodyne TDI RP105 series. It features a 20 A current rating and a 250 VAC voltage rating, designed for operation at 50 Hz or 60 Hz frequencies. The unit utilizes quick connect terminals for electrical termination and supports chassis mounting. Key specifications include a capacitance of 10 nF and a leakage current range of 0 A to 1.8 mA. The component measures 76 mm in length, 38 mm in height, and 40 mm in width. It holds UL, CSA, and EN compliance certifications.

Feature Summary

• Single-stage EMI/RFI attenuation for single-phase AC power lines
• Quick connect terminal interface for simplified wiring integration
• Chassis mount design for secure mechanical installation
• Certified for international safety standards including UL, CSA, and EN

Applications

• Industrial machinery power input stages
• Medical equipment power supplies
• Commercial IT infrastructure power distribution
• Test and measurement instrument power conditioning

Procurement Notes

Verify the specific capacitance value against project requirements, as similar part numbers in the RP105 series may vary (e.g., 4.7 nF vs 10 nF). Confirm that the quick connect terminal dimensions match the mating connector specifications. Ensure the chassis mounting hole pattern aligns with the enclosure design. Check that the 20 A continuous current rating exceeds the maximum load current of the application under all operating conditions.

Selection Notes

Select this model when a single-stage filter solution is sufficient for the required attenuation levels. The 20 A rating makes it suitable for higher power applications compared to lower-current variants. The compact form factor allows for dense packaging within equipment enclosures. Consider the leakage current specification if strict isolation limits are mandated by the end-product safety standards.

Part Context

This component belongs to the RP105 series of compact power line filters manufactured by Astrodyne TDI. The series offers various current ratings and capacitance values to suit different EMC requirements. The RP105-20-10-QD specifically denotes the 20 Ampere variant with 10 nanofarad capacitance. It is part of a broader portfolio of EMI suppression components designed for global market compliance.

Replacement Considerations

Direct substitutes within the same series include RP105-20-4.7-QD for lower capacitance needs. For higher current requirements, consider the RP105-30-4.7-QD. Cross-series replacements like the RP225 series offer dual-stage filtering but differ in physical dimensions and performance characteristics.
