RP185-3-4.7-W

Overview

The Astrodyne TDI RP185-3-4.7-W is a high-performance, single-stage IEC inlet power line filter designed for AC mains applications. It operates at a rated current of 3A and a voltage of 250VAC, with a working frequency range of 50Hz to 60Hz. The unit incorporates a capacitance value of 4.7nF to provide effective electromagnetic interference suppression. Designed for panel mounting, this component utilizes tab connectors for secure electrical termination. It complies with international safety standards including UL, CSA, and EN certifications.

Feature Summary

• Single-stage EMI filtering architecture integrated within an IEC inlet form factor
• High-performance noise attenuation capabilities for sensitive electronic equipment
• Compliant with major international safety and regulatory standards

Applications

• Industrial automation systems requiring compact EMI protection
• Process control equipment needing reliable signal integrity
• Medical devices demanding strict leakage current and noise management

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct terminal type and capacitance values. Confirm that the 3A rating aligns with the system's continuous load requirements. Check for updated compliance certificates relevant to the target market. Ensure panel cutout dimensions match the physical housing specifications provided in the mechanical drawings.

Selection Notes

Select this model when a combined IEC inlet and filter solution is required to save space. The 3A rating suits low-power control circuits rather than heavy machinery. Verify that the 4.7nF capacitance meets the specific leakage current limits of the end application. Consider the tab connector style for compatibility with existing wiring harnesses or PCB layouts.

Part Context

This component belongs to the RP185 series from Astrodyne TDI, which focuses on high-performance single-stage filtration. The series is engineered for applications where size constraints are critical but significant noise reduction is still necessary. It serves as a bridge between standard IEC connectors and advanced EMC filtering needs.

Replacement Considerations

Direct substitutes include other RP185 series variants with different current ratings, such as the RP185-6-4.7-W for higher current loads. Models like the RP185-1-.47-W offer lower capacitance options if leakage current is a primary constraint. Always verify pin-out and mounting hole patterns before swapping.
