RP220-12-4.7-S

Overview

The RP220-12-4.7-S is a single-phase, dual-stage power line filter from the Astrodyne TDI RP220 series. It features a 12 A current rating and a capacitance of 4.7 nF. The unit operates at 250 VAC and supports 50 Hz/60 Hz frequencies. It utilizes threaded post (M4) connections for secure mounting.

Feature Summary

• Dual-stage filtering architecture for enhanced EMI/EMI suppression
• High-performance design optimized for compact chassis integration
• Secure M4 threaded post termination for reliable electrical contact

Applications

• Medical equipment power inputs
• Industrial control systems
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'S' denotes the threaded post configuration distinct from other RP220 variants. Confirm RoHS compliance status with the manufacturer prior to final procurement. Ensure mechanical dimensions align with available chassis space. Validate that the 12A rating meets peak load requirements.

Selection Notes

Select this model when high attenuation in a small footprint is required. The dual-stage design offers superior noise reduction compared to single-stage alternatives. Ensure the application voltage does not exceed 250 VAC. Verify that the M4 terminal style matches existing wiring harnesses or busbar setups.

Part Context

This component belongs to the RP220 series, which provides high-performance EMC solutions. It is designed for applications requiring robust interference suppression in limited spaces. The series is widely used in sensitive electronic environments where signal integrity is critical.

Replacement Considerations

Direct substitutes include the RP220-12-4.7-QD if quick-connect terminals are acceptable instead of threaded posts. Other RP220 variants may be considered if current ratings differ, but capacitance and stage count must match for equivalent performance.
