PMR209MB5470M047R30

Overview

The KEMET PMR209MB5470M047R30 is a single-channel RC circuit from the PMR209 series, designed for electromagnetic interference and radio frequency interference suppression. It integrates a 47 nF metallized paper capacitor with a 47 Ω resistor, rated for 250 VAC and 630 VDC. The component features radial leads with a 15.2 mm pitch and ±30% resistance tolerance. Certified to UL, ENEC, cUL, and VDE standards, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a 47 nF capacitor and 47 Ω resistor in a single radial package
• Class X2 safety rating for AC line filtering applications
• Compliant with major international safety certifications including UL and VDE

Applications

• EMI/RFI suppression in AC power input stages
• Noise filtering for electronic equipment connected to mains supply
• Safety isolation circuits requiring Class X2 rated components

Procurement Notes

Verify the specific suffix R30 against the manufacturer's current datasheet to confirm lead form and packaging specifications. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range. Confirm that the 250 VAC rating aligns with the local mains voltage requirements. Check for RoHS compliance status if restricted substances are a constraint for the final assembly.

Selection Notes

Select this component when a combined RC filter is required for AC line noise reduction. The 47 nF capacitance and 47 Ω resistance provide specific attenuation characteristics suitable for general EMI suppression. The radial through-hole construction facilitates manual or standard automated insertion. Verify that the physical dimensions fit the available board space and that the lead spacing matches the PCB layout.

Part Context

This part belongs to the KEMET PMR209 series of metallized impregnated paper capacitors. These components are specifically engineered as safety capacitors for use across AC lines. The series offers various capacitance and resistance combinations to tailor filtering performance while maintaining strict adherence to international safety standards for consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 47 nF capacitance, 47 Ω resistance, 250 VAC rating, and Class X2 safety classification. Verify that any alternative component maintains the same radial lead configuration and mounting style. Cross-reference certification marks (UL, VDE) to ensure regulatory compliance equivalence in the target market.
