P409CP224M275AH221

Overview

The KEMET P409CP224M275AH221 is a radial leaded X2 safety film capacitor from the P409 series. It features a capacitance of 220 nF with a tolerance of ±20%. Rated for 275 VAC and 630 VDC, it utilizes paper dielectric construction. The component supports through-hole mounting with a 20.3 mm lead spacing and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Certified X2 class safety suppression for mains connection
• Paper dielectric construction for high voltage stability
• Compliant with international safety standards including UL, IEC, and CSA

Applications

• Electromagnetic interference (EMI) suppression in AC power supplies
• Cross-line filtering in household appliances
• Industrial equipment power input stages

Procurement Notes

Verify the specific suffix AH221 against official KEMET documentation to confirm lead length and packaging details. Ensure the application environment remains within the specified -40°C to +85°C operating range. Confirm that the 275VAC rating aligns with local mains voltage requirements and relevant safety certifications are recognized for the target market.

Selection Notes

Select this component when X2 safety certification is mandatory for cross-line applications. The 220nF value suits general EMI filtering needs. Verify physical dimensions fit the PCB layout due to the 20.3mm lead spacing. Consider the paper dielectric characteristics for long-term reliability in standard industrial environments.

Part Context

This part belongs to the KEMET P409 series of metallized paper capacitors designed specifically for safety applications. These components are engineered to fail open-circuit upon degradation, preventing electric shock hazards. The series is widely used in global markets due to its broad range of international approvals.

Replacement Considerations

Direct substitutes must match the 220nF capacitance, 275VAC rating, X2 safety class, and 20.3mm lead pitch. Verify equivalent certifications such as UL 60384-14 and IEC 60384-14. Alternative manufacturers like Vishay or Yageo offer comparable X2 paper capacitors if pin compatibility is maintained.
