P409CP224M275AH220

Overview

The KEMET P409CP224M275AH220 is a metallized paper film capacitor designed for X2 safety suppression applications. It features a capacitance of 220 nF with a tolerance of ±20%. The component is rated for 275 VAC and 275 VDC, with a DC voltage rating of 630 VDC. It utilizes through-hole radial mounting with a lead spacing of 20.3 mm. The physical dimensions are 24 mm in length, 11.3 mm in depth, and 16.5 mm in height. It operates within a temperature range of -40°C to +85°C and holds certifications including UL, EN/IEC, and CAN/CSA standards.

Feature Summary

• X2 class safety suppression capability for mains interference filtering
• Metallized paper dielectric construction for high reliability
• Compliance with international safety standards including UL and IEC

Applications

• Power supply input filtering
• EMI suppression circuits
• General purpose AC line coupling

Procurement Notes

Verify the specific suffix AH220 against official KEMET documentation to confirm lead spacing and termination details. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range. Confirm that the 275VAC rating aligns with local mains voltage requirements and safety regulations before integration into final equipment designs.

Selection Notes

Select this component when X2 safety certification is mandatory for AC line applications. The 20.3mm lead spacing suits standard PCB layouts requiring this pitch. Consider the paper dielectric characteristics for cost-sensitive designs where metallized polypropylene alternatives are not required. Verify that the 220nF value meets the circuit's filtering or snubbing requirements.

Part Context

This part belongs to the KEMET P409 series of metallized paper capacitors. The series is characterized by its use in safety-critical AC applications. Other variants in the series differ primarily in capacitance values, physical dimensions, and lead spacings while maintaining similar electrical ratings and safety approvals.

Replacement Considerations

Direct substitutes include other KEMET P409 series parts with identical electrical ratings and mechanical dimensions. Cross-brand replacements must match the X2 safety rating, 275VAC voltage, and 20.3mm lead pitch to ensure compatibility.
