Key electrical parameters include a DC voltage rating of 630 VDC and an integrated 47 Ω series resistor. Physical dimensions are 30.5 mm in length, 15.3 mm in width, and 22 mm in height, with a 25.4 mm lead spacing.

Feature Summary

• Integrated 47 Ohm series resistor for RC snubber functionality
• X2 safety class certification for mains interference suppression
• Paper dielectric construction for high reliability

Applications

• RC snubber circuits in power electronics
• EMI/RFI filtering in AC mains inputs
• Cross-line noise suppression in household appliances

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm the integrated resistance value and physical package dimensions. Ensure the selected variant matches the required lead spacing and thermal ratings for the target PCB layout. Cross-reference certification marks such as UL or EN/IEC 60384-14 with local regulatory requirements before finalizing procurement.

Selection Notes

Select this component when an integrated RC snubber solution is required for cross-line EMI suppression. The built-in resistor eliminates the need for separate discrete components, simplifying assembly. Verify that the 275 VAC rating aligns with the local mains voltage standards and that the 47 Ohm resistance value suits the specific damping requirements of the application circuit.

Part Context

This part belongs to the KEMET P409 series of X2 safety capacitors. These components are specifically engineered for electromagnetic interference suppression across AC mains lines. The series combines standard safety capacitor characteristics with integrated resistive elements to provide complete RC filter solutions in a single compact package.

Replacement Considerations

Substitutes must match the 220 nF capacitance, 275 VAC rating, and 47 Ohm integrated resistance. Verify equivalent X2 safety certifications and compatible operating temperature ranges. Ensure physical footprint and lead spacing compatibility with existing PCB layouts.
