PMR205AC6470M047R30

Overview

The KEMET PMR205AC6470M047R30 is a first-order low-pass RC EMI/RFI filter designed for through-hole mounting. It integrates a 0.47 µF film capacitor and a 47 Ω resistor within a single radial component. The device operates with a rated AC voltage of 125 VAC and features a lead pitch of 20.3 mm. Constructed with metalized paper foil dielectric, it provides effective noise suppression in electronic circuits while maintaining compliance with RoHS standards.

Feature Summary

• Integrates a 0.47 µF capacitor and 47 Ω resistor into a single radial package
• Functions as a first-order low-pass filter for EMI/RFI suppression
• Utilizes metalized paper foil dielectric technology

Applications

• General purpose EMI filtering in electronic equipment
• Power supply input stages requiring noise reduction
• Signal line protection against high-frequency interference

Procurement Notes

Verify the specific capacitance value against official datasheets, as conflicting data exists between 0.047 µF and 0.47 µF in available sources. Confirm the exact AC voltage rating (125 VAC vs 20 VAC) prior to integration. Ensure the 20.3 mm lead pitch matches the target PCB layout requirements to prevent mechanical installation errors.

Selection Notes

Select this component when a compact, single-unit solution is required for first-order filtering applications. The radial through-hole format suits prototyping and standard industrial enclosures. Consider the metalized paper foil construction for cost-effective noise attenuation where extreme temperature stability or high-frequency performance is not the primary constraint.

Part Context

This part belongs to the KEMET PMR205 series of RC filters. These components are engineered to replace discrete resistor-capacitor networks, saving board space and assembly time. The series is widely used in consumer electronics and industrial controls for basic electromagnetic interference mitigation on power and signal lines.

Replacement Considerations

PMR209MB5470M047R30 offers similar filtering characteristics but differs in physical dimensions and potentially voltage ratings. Verify pin compatibility and electrical specifications before substitution.
