RP225-3-3.3-QD

Overview

The Astrodyne TDI RP225-3-3.3-QD is a single-phase, dual-stage EMC/EMI power line filter designed for high-performance noise suppression. It features a current rating of 3 A and operates at voltages up to 250 VAC at 50/60 Hz. The unit incorporates a capacitance value of 3.3 nF (3300 pF) and utilizes quick connect termination style for circuit integration. Physical dimensions are approximately 51 mm in width, 40 mm in height, and 65 mm in length. Leakage current ranges from 0 to 1.8 mA. The component holds UL, CSA, and EN approvals.

Feature Summary

• Dual-stage filtering architecture for enhanced electromagnetic interference attenuation
• Quick connect termination style facilitates rapid installation on chassis or panels
• RoHS compliant construction meets environmental safety standards

Applications

• Single-phase electronic equipment requiring EMI/RFI noise reduction
• Medical devices adhering to strict leakage current limits
• Industrial control systems needing certified power line filtration

Procurement Notes

Verify the specific suffix QD confirms quick connect terminals against your schematic requirements. Confirm that the 3 A current rating aligns with your system's maximum load. Ensure chassis mounting provisions match the physical footprint of 51x40x65 mm. Check that input voltage does not exceed 250 VAC. Validate that leakage current specifications meet regulatory compliance for your target market.

Selection Notes

Select this model when dual-stage attenuation is required within a compact single-phase form factor. The quick connect interface suits applications where frequent maintenance or modular assembly is necessary. Consider the 3 A limit for low-power electronics rather than heavy machinery. Verify that the 3.3 nF capacitance provides adequate common-mode noise suppression for your specific frequency range without causing excessive inrush current issues.

Part Context

This component belongs to the RP225 series of power line filters from Astrodyne TDI. The series offers various current ratings and termination options. The RP225-3-3.3-QD specifically denotes the 3 A variant with quick connect pins. Other variants in the family include different amperage ratings such as 10 A or 20 A models. The series is widely used in commercial and industrial sectors for meeting global EMC directives.

Replacement Considerations

Direct substitutes may include other Astrodyne TDI RP225 series units with matching current ratings. Verify pinout compatibility for quick connect interfaces before swapping. Alternative manufacturers may offer similar dual-stage filters but require validation of approval certifications like UL and EN.
