RP187-3-4.7-W

Overview

The Astrodyne TDI RP187-3-4.7-W is a single-phase EMC/EMI line filter module designed for power line conditioning. It features a two-stage filtering architecture to suppress electromagnetic interference across the 50 Hz and 60 Hz operating frequency range. The unit supports a rated voltage of 250 VAC and handles a current capacity of 3 A. Electrical connections are established via wire leads, while the input interface utilizes an IEC 320-C14 connector. This configuration ensures effective noise attenuation for sensitive electronic equipment requiring stable power supply integrity.

Feature Summary

• Two-stage filtering architecture for enhanced noise suppression
• Integrated IEC 320-C14 input connector for standardized mating
• Wire lead termination for flexible circuit integration

Applications

• Medical equipment power supplies
• Industrial control systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm terminal type and capacitance values. Ensure the IEC 320-C14 inlet compatibility matches the downstream equipment requirements. Confirm regulatory compliance certifications such as UL or CSA are required for the target market before finalizing procurement specifications.

Selection Notes

Select this component when a compact two-stage filter solution is required for 3 A applications. The wire lead output allows for direct PCB or chassis mounting flexibility. Verify that the 250 VAC rating aligns with the local mains voltage standards. Consider the physical dimensions and thermal environment during system design to ensure adequate clearance and heat dissipation.

Part Context

This model belongs to the RP187 series of power line filters from Astrodyne TDI. The series provides various configurations for single-phase applications. The RP187 designation indicates a specific form factor and electrical profile within the broader product family, distinguishing it from other series like RP100 or RP135 which may offer different mounting styles or current ratings.

Replacement Considerations

Consult the official replacement guide for cross-reference part numbers. Ensure any substitute maintains the same 3 A current rating, 250 VAC voltage rating, and IEC 320-C14 interface. Verify that the replacement offers equivalent two-stage filtering performance and compatible terminal types.
