Procurement Notes

Verify the specific suffix R30 against official KEMET documentation to confirm packaging details and exact mechanical tolerances. Ensure the 25.4 mm lead spacing matches the target PCB footprint requirements. Confirm that the 220-ohm resistance value aligns with the intended circuit impedance and current handling capabilities before finalizing procurement.

Selection Notes

Select this component when a combined RC network is required for first-order filtering applications. The 25.4 mm lead pitch dictates the necessary board layout constraints. Consider the 220-ohm series resistance impact on voltage drop and power dissipation relative to the load current. Verify compatibility with the 250 VAC operating environment and ensure the metallized paper construction meets the specific safety and regulatory standards required for the end application.

Part Context

This part belongs to the KEMET PMR209 series of RC filters. These components are engineered for general-purpose EMI suppression tasks. The series offers various capacitance and resistance combinations to suit different filtering needs while maintaining a standardized radial form factor suitable for automated or manual insertion processes.

Replacement Considerations

Cross-reference alternative parts from other manufacturers offering identical 0.47 µF capacitance, 220 ohm resistance, and 25.4 mm lead spacing. Verify that substitute components meet the same 250 VAC rating and operate within the -40°C to +85°C temperature range to ensure functional equivalence.
