RP187-10-4.7-W

Overview

The Astrodyne TDI RP187-10-4.7-W is a high-performance dual-stage IEC inlet power line filter belonging to the RP187 series. It features a C14 connector interface and is rated for a continuous current of 10A at 250VAC. The unit incorporates a capacitance value of 4.7nF to provide effective electromagnetic interference suppression. Designed for chassis or panel mounting, this single-phase filter operates within standard 50Hz and 60Hz frequency ranges. It integrates both common-mode and differential-mode filtering stages to ensure compliance with stringent emission standards in sensitive electronic applications.

Feature Summary

• Dual-stage filtering architecture providing enhanced attenuation across broad frequency bands
• Integrated IEC C14 inlet connector for standardized power connection
• Compact form factor designed for direct equipment integration

Applications

• Medical diagnostic imaging equipment requiring low leakage and high noise immunity
• Industrial control systems and automation panels
• Telecommunications infrastructure power supplies
• High-precision laboratory instrumentation

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to confirm terminal type and certification requirements. Ensure the operating voltage and current ratings align with the system design specifications. Confirm regulatory compliance status such as UL or CE marks if required by the target market. Check for any recent component updates that may affect pinout or mechanical dimensions before finalizing procurement orders.

Selection Notes

Select this model when dual-stage performance is necessary to meet strict EMI/EMC regulations without external components. The integrated C14 connector simplifies assembly compared to discrete filter designs. Consider the 10A rating and 4.7nF capacitance for balancing leakage current limits against noise suppression needs. Evaluate space constraints as the dual-stage design may require slightly more volume than single-stage alternatives.

Part Context

This component is part of the Astrodyne TDI RP187 series, which specializes in high-performance filtered IEC modules. The series is engineered for applications demanding superior noise rejection in compact spaces. Unlike general-purpose filters, these units combine filtering elements directly with the power inlet, streamlining the power entry module design for OEMs.

Replacement Considerations

Direct replacements must match the 10A current rating, 250VAC voltage, and 4.7nF capacitance. Verify that substitute models offer comparable dual-stage attenuation characteristics. Ensure mechanical compatibility with existing C14 receptacles and mounting holes. Cross-reference regulatory approvals to maintain compliance in certified end-products.
