RP220-12-.47-S

Overview

The RP220-12-.47-S is a single-phase, dual-stage power line filter from the Astrodyne TDI RP220 series. It features a high-performance design with a rated current of 12 A and a capacitance of 0.47 nF. The unit supports a voltage rating of 250 VAC and operates at frequencies of 50 Hz or 60 Hz. It utilizes quick connect termination for electrical connections and is designed for chassis mount installation. Key specifications include an 800 uA leakage current and compliance with UL, CSA, and EN standards.

Feature Summary

• Dual-stage filtering architecture for enhanced noise attenuation
• High-performance electromagnetic interference suppression
• Chassis mount configuration for secure mechanical integration

Applications

• Industrial machinery power conditioning
• Medical equipment EMI protection
• Test and measurement instrumentation filtering

Procurement Notes

Verify that the suffix 'S' corresponds to the specific termination style required for your assembly, as it differs from other variants like 'QD'. Confirm chassis mounting dimensions and hole patterns match your enclosure design. Ensure the 12 A current rating aligns with the maximum load requirements of the protected circuit to prevent thermal overload during continuous operation.

Selection Notes

Select this model when dual-stage attenuation is necessary for sensitive electronics operating on single-phase AC lines. Compare against the RP220-12-.47-QD if quick-connect terminals are preferred over stud-style terminations. Evaluate the 0.47 nF capacitance value against system leakage current limits, as higher capacitance may impact safety grounding requirements in medical or isolated applications.

Part Context

This component belongs to the RP220 series, which provides robust EMI/RFI filtering solutions. It complements other models in the lineup such as the RP220-6-4.7-QD and RP220-20-1-QD, offering varying current ratings and capacitance values. The series is engineered for reliability in demanding environments requiring strict compliance with international safety and emissions standards.
