RP182CD-3-2.2-QD

Overview

The Astrodyne TDI RP182CD-3-2.2-QD is a single-phase, dual-stage EMI/EMC power line filter designed for chassis mounting. It features quick connect terminals and supports a rated voltage of 250 VAC with a current rating of 3 A at 50/60 Hz. The unit incorporates a capacitance value of 2.2 nF and maintains a low leakage current of 340 µA. Certified to UL, CSA, and EN standards, it operates within a temperature range of -25°C to +85°C. Physical dimensions are approximately 75.8 mm in length.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• IEC C14 inlet compatibility for direct equipment integration
• Low leakage current design suitable for sensitive medical or IT applications
• Quick-connect terminal style for simplified assembly

Applications

• Medical equipment power inputs
• Information technology (IT) hardware
• Industrial control systems
• Test and measurement instruments

Procurement Notes

Verify that the specific application requires the 2.2 nF capacitance value, as this influences leakage current characteristics. Confirm that the operating environment stays within the specified -25°C to +85°C temperature range. Ensure the chassis mounting method aligns with the physical dimensions provided. Check for any specific regional certification requirements beyond UL, CSA, and EN before finalizing procurement.

Selection Notes

Select this component when high-performance differential and common-mode noise suppression is required in a compact form factor. The dual-stage design offers superior attenuation compared to single-stage alternatives. Consider the 3 A current rating against peak load requirements. The IEC inlet interface simplifies integration into standard power cords. Evaluate the 340 µA leakage current against safety regulations for the end device.

Part Context

This model belongs to the RP182CD series, which focuses on ultra-high performance filtering for space-constrained applications. The series is engineered to meet stringent EMC standards while maintaining low profile dimensions. It complements other Astrodyne TDI filters by offering a balance between high attenuation and minimal electrical footprint for critical power lines.

Replacement Considerations

Direct substitutes may include other RP182CD variants with different capacitance values if leakage current constraints differ. Verify that alternative models maintain the same 3 A rating and 250 VAC specification. Ensure replacement units support quick-connect termination and IEC C14 inlet compatibility to preserve mechanical fit.
