RP186-3-47-W

Overview

The Astrodyne TDI RP186-3-47-W is a single-phase, single-stage power line filter designed for chassis or panel mounting. It features an IEC C14 inlet and wire lead outputs, rated for 3 A current at 250 VAC. The unit incorporates a 47 nF capacitance to provide EMI/RFI suppression in 50 Hz and 60 Hz systems. Certified under UL and CSA standards, this component ensures compliance with electromagnetic interference regulations for sensitive electronic equipment.

Feature Summary

• Integrates an IEC 320-C14 inlet connector for standardized power connection
• Provides single-stage EMI/RFI attenuation for noise reduction
• Utilizes wire leads for flexible circuit integration

Applications

• Medical diagnostic equipment requiring strict EMI control
• Industrial automation control panels
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix designation against official datasheets to confirm terminal configuration and certification status. Ensure the selected variant matches the required voltage and current ratings for the target application. Cross-reference manufacturer documentation to validate compliance with regional safety standards before procurement.

Selection Notes

Select this model when a compact, single-phase filter with an integrated IEC inlet is required. Confirm that the 3 A rating and 47 nF capacitance align with system leakage current limits and noise suppression needs. Evaluate physical dimensions and mounting constraints to ensure compatibility with the enclosure design.

Part Context

This component belongs to the RP186 series of ultra-high-performance single-stage filters from Astrodyne TDI. The series is engineered for applications demanding significant noise attenuation within a small form factor. It serves as a critical interface between the AC power source and sensitive downstream electronics.

Replacement Considerations

Direct substitutes must match the IEC C14 inlet, 3 A rating, and 47 nF capacitance. Verify equivalent certification approvals (UL/CSA) and physical footprint compatibility. Consult manufacturer cross-reference lists for verified alternative part numbers.
