RP187-20-4.7-QD

Overview

The RP187-20-4.7-QD is a single-phase power line filter module from the Astrodyne TDI RP187 series, designed for high-performance EMI/RFI suppression. It features a C20 IEC inlet and supports a rated current of 20 A at 250 VAC. The unit incorporates a dual-stage filtering architecture with a capacitance of 4.7 nF and maintains a leakage current of 800 uA. Operating within a temperature range of -25°C to +40°C, it utilizes quick disconnect tab connectors for chassis mounting. Dimensions are approximately 65 mm in length.

Feature Summary

• Dual-stage EMI/RFI suppression architecture for enhanced noise attenuation
• IEC C20 inlet configuration with quick disconnect tab connectors
• Agency approved to UL1283 and EN60939 standards

Applications

• Industrial equipment requiring robust EMI protection
• Medical devices adhering to strict leakage current limits
• High-performance computing hardware

Procurement Notes

Verify that the specific application environment remains within the stated operating temperature range of -25°C to +40°C. Confirm compatibility with the 20 A rated current and 250 VAC voltage specifications. Ensure the chassis mounting style and quick disconnect tab connector type align with the system's wiring requirements. Check for required agency approvals such as UL1283 or EN60939 compliance for the target market.

Selection Notes

Select this model when a C20 inlet is required alongside a 20 A capacity. The dual-stage design offers superior filtering compared to single-stage alternatives. Consider the 800 uA leakage current limit if safety isolation is critical. Verify physical dimensions against available panel space, noting the 65 mm length.

Part Context

This component belongs to the Astrodyne TDI RP187 series of filtered IEC modules. These units are engineered for high-performance applications where significant electromagnetic interference suppression is necessary. The series typically includes various current ratings and capacitance values to suit different power distribution needs.

Replacement Considerations

Direct substitutes may include other RP187 series variants with matching current and voltage ratings. Verify that any replacement maintains the C20 inlet and quick disconnect termination style. Ensure equivalent leakage current and capacitance values to preserve circuit performance.
