RP186-12-.47-W

Overview

The RP186-12-.47-W is a single-stage power line filter from the Astrodyne TDI RP186 series. It is designed for high-performance electromagnetic interference suppression in AC power circuits. The component features a capacitance value of 47 nF and is rated for a current of 12 A at 250 VAC. It utilizes quick connect terminals for electrical interfacing and supports chassis or panel mounting configurations. The unit operates within standard industrial frequency ranges of 50 Hz and 60 Hz.

Feature Summary

• Single-stage filtering architecture for effective noise attenuation
• High current handling capability suitable for demanding loads
• Quick connect terminal interface for simplified wiring
• Compliance with international safety standards including UL and CSA

Applications

• Industrial machinery power input stages
• Medical equipment power conditioning
• Commercial IT infrastructure power distribution
• Test and measurement instrument power supplies

Procurement Notes

Verify the exact suffix designation, as datasheets may list RP186-12-47-QD or similar variants. Confirm terminal type and mounting hardware requirements against the specific application board design. Ensure voltage and current ratings exceed maximum operational peaks to maintain safety margins and compliance with regulatory certifications.

Selection Notes

Select this model when high attenuation performance is required in a compact single-stage form factor. Compare leakage current specifications against sensitive medical or audio applications. Verify that the 12 A rating aligns with the system's continuous load requirements. Consider the physical dimensions for chassis integration constraints.

Part Context

This component belongs to the RP186 series, which focuses on ultra-high performance single-stage filtration. It complements other Astrodyne TDI filters like the RP135 and RP100 series by offering higher current capacity and specialized attenuation characteristics for stringent EMI/EMC environments.

Replacement Considerations

Direct substitutes include the RP186-12-47-QD variant, which shares identical electrical parameters but may differ in terminal style or packaging. Cross-reference with RP135 series models if lower current ratings are acceptable.
