RP190-3-4.7

Overview

The Astrodyne TDI RP190-3-4.7 is a compact, single-stage power line filter designed for PCB mounting applications. It supports a current rating of 3 A and operates at voltage ratings up to 250 VAC. The component functions within a frequency range of DC to 60 Hz and provides high-potential insulation with a hipot rating of 2500 VDC. This single-phase filter is engineered for efficient electromagnetic interference suppression in space-constrained electronic assemblies.

Feature Summary

• Compact form factor optimized for printed circuit board integration
• Single-stage filtering architecture for efficient noise reduction
• High dielectric strength insulation capability

Applications

• Space-constrained electronic equipment requiring PCB-mounted EMI suppression
• Single-phase AC power input stages in consumer or industrial electronics
• Applications necessitating low-profile electromagnetic interference filtration

Procurement Notes

Verify the specific datasheet version and compliance documentation prior to procurement. Confirm that the 3 A current rating and 250 VAC voltage limits align with the target system requirements. Ensure PCB layout accommodates the physical dimensions and terminal configuration specified in the official manufacturer documentation to maintain electrical safety and performance integrity.

Selection Notes

Select this component when a single-stage solution is sufficient for the required attenuation levels. The 3 A rating defines the maximum continuous current capacity. Verify that the PCB mounting style meets the mechanical constraints of the enclosure. Ensure the operating environment remains within the specified thermal and electrical boundaries defined by the manufacturer.

Part Context

This component belongs to the RP190 series from Astrodyne TDI, which specializes in compact power line filters. The series is characterized by its suitability for direct PCB installation, offering a balance between filtering performance and minimal footprint. It serves as a targeted solution for managing conducted emissions in single-phase power systems where space is limited.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Generic cross-references may not match the specific capacitance values or mounting characteristics. Ensure any substitute maintains the same single-stage topology and PCB interface compatibility.
