RP110-20-4.7-QD

Overview

The Astrodyne TDI RP110-20-4.7-QD is a compact, single-phase, single-stage power line filter designed for chassis mounting. It features a 20 A current rating and operates at 250 VAC with a working frequency of 50 Hz or 60 Hz. The unit utilizes quick connect tab terminals for electrical termination and includes a 4.7 nF capacitance value. Certified under cURus and EN60939 standards, it provides effective electromagnetic interference suppression in a space-saving form factor suitable for high-performance applications.

Feature Summary

• Compact single-phase single-stage design for efficient EMI suppression
• Quick connect tab terminal configuration for simplified wiring
• Chassis mount style for secure installation in equipment enclosures

Applications

• Industrial control systems requiring compact EMI filtering
• Medical equipment power input stages
• Information technology hardware power supplies

Procurement Notes

Verify the specific datasheet version to confirm compliance certifications such as cURus and EN60939. Ensure the quick connect tab dimensions match the mating connector requirements. Confirm that the 20 A continuous current rating aligns with the system load profile and ambient temperature conditions to prevent thermal derating issues during operation.

Selection Notes

Select this model when a single-stage solution is sufficient for the required attenuation levels. The 20 A rating distinguishes it from lower-current variants like the RP110-10-4.7-QD. Verify that the chassis mounting footprint fits within the available enclosure space. Consider the leakage current specifications if strict safety isolation limits are mandated by the end-use application standards.

Part Context

This component belongs to the RP110 series of power line filters from Astrodyne TDI. The series offers various current ratings and capacitance values to suit different power handling needs. The RP110-20-4.7-QD specifically addresses applications needing moderate current capacity with a standardized 4.7 nF common-mode capacitance configuration.

Replacement Considerations

Direct substitutes include other RP110 series models with identical mechanical footprints but different current or capacitance ratings, such as RP110-10-4.7-QD. Cross-series replacements require verification of mounting dimensions and terminal types.
