RP185-3-4.7-QD

Overview

The RP185-3-4.7-QD is a single-phase, high-performance power line filter from the Astrodyne TDI RP185 series. It features a 3 A current rating and a 250 VAC voltage rating, designed for operation at 50 Hz or 60 Hz frequencies. The unit incorporates a 4.7 nF capacitance value and utilizes an IEC C14 inlet connector with quick-connect terminals. Constructed for chassis mounting, this two-stage filter provides effective EMI/EMI suppression while maintaining low leakage current characteristics suitable for sensitive electronic equipment.

Feature Summary

• Single-stage IEC inlet filter design for efficient electromagnetic interference suppression
• Quick-connect terminal configuration for simplified integration into power entry modules
• Chassis mount construction ensuring stable physical installation in industrial enclosures

Applications

• Power supply units requiring compact EMI filtering
• Battery chargers needing reliable noise reduction
• Portable electronic devices with strict emission standards

Procurement Notes

Verify the specific datasheet version for the RP185-3-4.7-QD to confirm compliance certifications such as UL, CSA, and EN. Ensure that the quick-connect terminal pitch matches your PCB or harness requirements. Confirm the operating temperature range aligns with your system's thermal environment before finalizing procurement decisions.

Selection Notes

Select this component when a single-phase, 3 A rated filter with an integrated IEC inlet is required. The 4.7 nF capacitance offers a balance between attenuation performance and leakage current limits. Consider the chassis mount style and quick-connect interface for ease of assembly in space-constrained applications compared to panel-mount alternatives.

Part Context

This model belongs to the RP185 series of high-performance single-stage filters. The series typically covers various current ratings and capacitance values to suit different power entry module configurations. The RP185-3-4.7-QD specifically targets applications requiring moderate current handling with standard mains frequency operation.

Replacement Considerations

Check for direct substitutes within the RP185 series with similar current and capacitance ratings. Verify compatibility of the IEC C14 inlet and quick-connect terminal dimensions against existing board layouts or harnesses before substituting.
