RP185-3-0-QD

Overview

The RP185-3-0-QD is a high-performance single-stage IEC inlet power line filter manufactured by Astrodyne TDI. Designed for 250 VAC operation at 60 Hz, it supports a continuous current rating of 3 A. The component features a compact form factor with dimensions of 76.5 mm in length and 40 mm in width. It utilizes a quick disconnect terminal interface for installation. The unit incorporates 0 nF capacitance to minimize leakage current, ensuring compliance with safety standards including UL and cURus certifications.

Feature Summary

• Single-stage EMI filtering architecture designed for efficient noise attenuation
• IEC inlet connector configuration for direct equipment integration
• Quick disconnect terminals facilitate rapid assembly and maintenance
• Low leakage current design compliant with medical and industrial safety regulations

Applications

• Medical diagnostic and therapeutic equipment
• Industrial control systems
• Information technology hardware
• Test and measurement instruments

Procurement Notes

Verify the specific datasheet revision and certification status (UL/cURus) prior to procurement. Confirm that the 0 nF capacitance meets the strict leakage current requirements of your target application. Ensure mechanical compatibility with the designated IEC inlet socket. Check for any recent supply chain constraints or alternative package options if standard availability is limited.

Selection Notes

Select this model when a compact, single-stage solution is required for 3 A circuits. The 0 nF capacitor value makes it suitable for applications with stringent leakage current limits. Verify that the chassis or panel thickness accommodates the quick disconnect mounting style. Compare against multi-stage alternatives only if higher attenuation at lower frequencies is necessary.

Part Context

This component belongs to the RP185 series of high-performance power line filters from Astrodyne TDI. The series is engineered for environments requiring reliable EMI suppression in space-constrained designs. The RP185-3-0-QD variant specifically targets low-leakage applications through its minimal capacitance configuration while maintaining effective differential mode noise reduction.

Replacement Considerations

Direct substitutes include other RP185 series variants with different current ratings or capacitance values. Cross-reference with RP185-3-X-QD models where X denotes the capacitance value. Ensure replacement units maintain the same IEC inlet interface and quick disconnect terminal type to preserve mechanical fit.
