RP225-3-4.7-W

Overview

The RP225-3-4.7-W is a single-phase, two-stage power line filter from the Astrodyne TDI RP225 series. It features a dual-stage design for high-performance electromagnetic interference suppression. The unit is rated for 250 VAC and supports a continuous current of 3 A. It utilizes a 4.7 nF capacitance value to manage noise. The component employs wire termination for electrical connections and is designed for chassis mounting. It operates at standard frequencies of 50 Hz and 60 Hz.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• Chassis mount construction for secure installation
• Wire termination configuration for circuit integration

Applications

• Industrial equipment requiring EMI suppression
• Medical device power inputs
• General purpose electronic systems

Procurement Notes

Verify the specific datasheet version for the RP225-3-4.7-W to confirm exact leakage current limits and insertion loss curves. Ensure the wire termination style matches the system harness requirements. Confirm compliance certifications such as UL or EN standards are valid for the target market. Check for any recent manufacturing updates that may affect physical dimensions or terminal specifications.

Selection Notes

Select this model when a two-stage filter is required for a 3 A single-phase application. The 4.7 nF capacitance provides a specific balance between attenuation and leakage current. Compare against single-stage alternatives if space constraints allow, noting the increased size of dual-stage units. Verify that the chassis mounting method aligns with the enclosure design. Ensure the operating temperature range meets environmental conditions.

Part Context

This component belongs to the RP225 series of power line filters by Astrodyne TDI. The series offers various current ratings and termination options. The RP225 designation indicates a specific form factor and performance tier within the manufacturer's portfolio. Other variants in the series differ primarily in current capacity and connection type while maintaining similar filtering principles.

Replacement Considerations

Direct substitutes include other RP225 series models with identical current and capacitance ratings but different terminations, such as RP225-3-4.7-QD. Cross-series replacements require careful verification of mounting dimensions and electrical characteristics to ensure compatibility.
