RP186-12-4.7-W

Overview

The Astrodyne TDI RP186-12-4.7-W is an ultra-high performance single-stage power line filter from the RP186 series. It features a compact design with a rated voltage of 250 VAC and a current rating of 12 A. The unit incorporates a 4.7 nF capacitance value and utilizes quick connect terminals for electrical connections. Designed for panel mounting, it operates at standard frequencies of 50 Hz and 60 Hz. The filter provides effective electromagnetic interference suppression while maintaining low leakage current characteristics suitable for sensitive electronic equipment.

Feature Summary

• Ultra-high performance single-stage filtering architecture
• Compact form factor designed for space-constrained panel installations
• Integrated IEC inlet configuration for simplified power entry

Applications

• Medical imaging systems requiring strict EMI compliance
• Industrial control panels with high-density mounting requirements
• Test and measurement equipment sensitive to line noise

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm terminal type and mounting style. Ensure the selected variant matches the required current and voltage ratings for the target application. Confirm regulatory compliance certifications such as UL or EN standards are present on the documentation before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and availability status.

Selection Notes

Select this component when a single-stage solution offers sufficient attenuation for the specific noise spectrum encountered. Compare the physical dimensions against available panel cutout space to ensure mechanical fit. Evaluate the 12 A current rating against peak load requirements to prevent thermal overload. Consider the quick connect termination method for assembly speed versus soldered alternatives if higher vibration resistance is needed.

Part Context

This model belongs to the RP186 series, which focuses on delivering high-performance filtering in a reduced footprint compared to traditional chassis-mounted units. The series targets applications where space is limited but stringent electromagnetic compatibility standards must be met. It represents a balance between performance density and installation flexibility for modern electronic enclosures.

Replacement Considerations

Direct substitutes within the same series include RP186-12-4.7-QD for chassis mount variants or RP186-12-4.7-S for stud mount options. Verify that alternative part numbers maintain identical electrical parameters including the 4.7 nF capacitance and 12 A rating. Ensure mechanical mounting interfaces match the existing enclosure design to avoid modification.
