RP188-3-4.7-QD

Overview

The RP188-3-4.7-QD is a single-phase EMC/EMI power line filter module from the Astrodyne TDI RP188 series. It features an IEC C14 inlet connector and utilizes quick-connect terminals for PCB mounting. The unit is rated for 3 A current at 250 V AC with a 50/60 Hz operating frequency. Internal components include a DPST switch, a 2-pole fuse holder, and a 4.7 nF capacitance value for noise suppression.

Feature Summary

• Integrates IEC C14 inlet, DPST switch, and fuse holder in a single compact module
• Employs quick-connect terminal interface for efficient printed circuit board assembly
• Provides single-stage EMI/EMC filtering capability for general-purpose applications

Applications

• General purpose electronic equipment power entry
• Industrial control systems requiring filtered AC input
• Medical devices needing compliant power line filtering

Procurement Notes

Verify that the required fuse rating matches the internal holder specifications before installation. Confirm that the quick-connect terminal dimensions align with the target PCB footprint. Ensure the operating environment temperature remains within the specified range to maintain component reliability and filter performance standards.

Selection Notes

Select this module when a combined switching, fusing, and filtering solution is required for space-constrained designs. The 3 A rating suits low-power electronics, while the integrated switch allows direct mains isolation without additional external components. Verify compatibility with downstream circuitry voltage requirements.

Part Context

This component belongs to the RP188 series of filtered IEC power entry modules manufactured by Astrodyne TDI. The series offers various current ratings and capacitance values to suit different electromagnetic interference suppression needs. The RP188 designation indicates a specific form factor optimized for standard IEC inlet integration.

Replacement Considerations

Direct substitutes include the RP188H-3-4.7-QD variant. Verify mechanical mounting differences and terminal types between standard and H-series versions before substitution to ensure physical compatibility with the existing chassis or PCB layout.
