RP186-1-4.7-QD

Overview

The RP186-1-4.7-QD is a single-stage EMI/EMC power line filter module manufactured by Astrodyne TDI, designed for IEC inlet applications. It features a rated current of 1 A and operates at voltages up to 250 V AC at 50/60 Hz. The component utilizes a capacitance value of 4.7 nF to provide noise suppression. Physical dimensions include a length of 57.2 mm, with leakage current specifications documented at 800 uA and 400 uA under specific test conditions.

Feature Summary

• Single-stage design for compact integration into IEC inlet configurations
• Provides electromagnetic interference (EMI) and radio frequency interference (RFI) filtering
• Engineered for efficient power conversion support in regulated systems

Applications

• Power supply units requiring input noise suppression
• Battery charger circuits needing EMI mitigation
• Portable electronic devices with strict EMC compliance requirements

Procurement Notes

Verify the exact datasheet version before procurement, as specifications such as leakage current may vary based on testing standards. Confirm that the 57.2 mm dimension aligns with your chassis or PCB layout constraints. Ensure the 1 A rating meets the maximum load requirements of your target application without derating issues. Cross-reference the 4.7 nF capacitance value against your circuit's impedance matching needs.

Selection Notes

Select this component when a single-stage solution is sufficient for your EMI reduction goals. The 1 A current rating suits low-power consumer and industrial electronics. Consider the physical footprint of 57.2 mm during mechanical design. Verify compatibility with IEC inlet connectors commonly used in global markets. Evaluate if the 4.7 nF capacitance provides adequate attenuation for your specific noise spectrum.

Part Context

This module belongs to the RP186 series from Astrodyne TDI, which specializes in power line filters. The series is characterized by ultra-high performance characteristics suitable for demanding environments. Similar models in the lineup, such as the RP186-1-2.2-QD, offer different capacitance values like 2.2 nF, allowing designers to tune filtering performance based on specific circuit requirements and space limitations.

Replacement Considerations

The RP186-1-2.2-QD serves as a functional substitute within the same series, offering identical current and voltage ratings but with a reduced capacitance of 2.2 nF instead of 4.7 nF. Designers must verify that the lower capacitance still meets their specific EMI suppression targets. No other direct substitutes are confirmed in public documentation.
