Procurement Notes

Verify the specific suffix AH331 against official KEMET documentation to confirm exact physical dimensions and termination specifications. Ensure the procurement channel provides valid RoHS compliance declarations and original manufacturer traceability. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing standards before finalizing orders.

Selection Notes

Select this component when designing circuits requiring X2 safety certification for AC line applications. The 220 nF value and 275 VAC rating suit standard mains voltage environments. Verify that the 25.4 mm lead pitch fits the target PCB layout and that the paper dielectric characteristics align with the thermal and electrical requirements of the specific snubber or suppression topology.

Part Context

This part belongs to the KEMET P409 series of paper dielectric capacitors. These components are engineered specifically for high-reliability safety applications where failure must not create shock hazards. The series supports various capacitance values while maintaining consistent safety ratings and mechanical form factors suitable for industrial and consumer AC power supplies.

Replacement Considerations

Direct substitutes include other KEMET P409 series parts with identical voltage and capacitance ratings but different case sizes, such as P409EL474M275AH470 for higher capacitance needs. Ensure any replacement maintains the X2 safety classification and compatible lead spacing for direct board integration without redesign.
