RP182CS-3-4.7-QD

Overview

The Astrodyne TDI RP182CS-3-4.7-QD is a single-stage power line filter designed for IEC inlet applications. It features a 250 VAC voltage rating and supports a current capacity of 3 A at operating frequencies of 50 Hz and 60 Hz. The unit utilizes tab connectors for termination and employs chassis mount installation methods. Key electrical specifications include a capacitance value of 4.7 nF and a leakage current of 0 A. The component measures 65 mm in length and 23.1 mm in height, adhering to CSA, EN60939, and UR compliance standards.

Feature Summary

• Single-stage filtering architecture for effective EMI suppression
• Integrated IEC inlet receptacle design for streamlined integration
• Chassis mount configuration with tab connector terminations

Applications

• Power supply input stages requiring IEC inlet compatibility
• Chassis-mounted electronic equipment needing compact filtering
• Low to mid-range power inverters and control systems

Procurement Notes

Verify the specific suffix QD against official manufacturer documentation to confirm terminal type and mounting style. Ensure the 3 A current rating aligns with system requirements. Confirm that the 250 VAC rating meets operational voltage needs. Check for required certifications such as UL or CSA depending on regional regulations. Validate physical dimensions for chassis clearance before finalizing procurement.

Selection Notes

Select this model when an integrated IEC inlet is preferred over separate receptacles. The single-stage design suits applications where moderate attenuation suffices. Verify that the tab connector interface matches existing wiring harnesses. Consider the 3 A limit for load calculations. Ensure the chassis mount footprint fits within the designated enclosure space without interference.

Part Context

This component belongs to the RP182CS series from Astrodyne TDI, which focuses on high-performance single-stage filters. The series targets applications requiring reliable EMI suppression in compact form factors. It complements other models like the RP186 and RP100 by offering a specialized IEC inlet variant. The design emphasizes ease of installation through standardized mounting and connection methods.

Replacement Considerations

Direct substitutes may include variants within the same RP182CS family with different capacitance values, such as RP182CS-3-3.3-QD. Cross-reference pinouts and mechanical dimensions to ensure compatibility. Verify that alternative parts maintain equivalent current and voltage ratings.
