RP220-20-4.7-S

Overview

The RP220-20-4.7-S is a single-phase, two-stage high-performance power line filter from the Astrodyne TDI RP220 series. It features a 250 VAC voltage rating and supports a continuous current of 20 A. The unit utilizes quick connect terminals for electrical interfacing and is designed for chassis mounting. Key specifications include a capacitance value of 4.7 nF, a leakage current of 1.8 mA, and operation at standard frequencies of 50 Hz and 60 Hz. The component complies with UL, CSA, and EN standards.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• High-performance design optimized for demanding electromagnetic interference suppression
• Quick connect terminal configuration for simplified circuit integration

Applications

• Power supply units requiring EMI reduction
• Battery charging systems
• Portable electronic devices
• Energy-efficient industrial equipment

Procurement Notes

Verify that the specific part number matches the required 20 A current rating and 4.7 nF capacitance. Confirm compliance with UL, CSA, and EN certifications for your target market. Ensure the chassis mount style and quick connect terminals align with your enclosure design and wiring harness specifications before finalizing procurement.

Selection Notes

Select this model when a two-stage filter is necessary for superior noise rejection compared to single-stage alternatives. The 20 A rating suits moderate-to-high current applications. Verify that the 1.8 mA leakage current is acceptable for sensitive safety grounding requirements. Ensure the physical dimensions fit the available chassis space.

Part Context

This component belongs to the RP220 series, which provides dual-stage filtering solutions. It differs from the RP130 series (single-stage) and the RP600 series (DC filters). The RP220 series is characterized by its two-stage topology and versatility in AC power line applications.

Replacement Considerations

Direct substitutes within the same series include RP220-6-4.7-QD, RP220-16-4.7-W, and RP220-20-10-S. Note that these variants differ in current ratings, terminal types, or capacitance values. Cross-series replacements like RP130-20-4.7-S offer single-stage performance instead of dual-stage.
