P409CP224M275AH330

Overview

The KEMET P409CP224M275AH330 is a radial leaded X2 safety capacitor from the P409 series, utilizing metallized paper dielectric. It features a capacitance of 220 nF with a tolerance of ±20%. Rated for 275 VAC and 630 VDC, it supports a maximum operating temperature of +85°C and a minimum of -40°C. The component has a lead spacing of 20.3 mm and includes an integrated discharge resistor of 33 Ω. Dimensions are 24 mm in length, 11.3 mm in depth, and 16.5 mm in height.

Feature Summary

• Integrated discharge resistor for safe voltage decay
• X2 class safety certification for mains interference suppression
• Metallized paper dielectric construction

Applications

• Cross-line electromagnetic interference (EMI) filtering
• Power supply input stages
• General purpose AC motor circuits

Procurement Notes

Verify the specific suffix AH330 to confirm the presence of the integrated 33 Ω discharge resistor, as standard P409 variants may lack this feature. Ensure the 20.3 mm lead pitch matches the target PCB footprint. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this component when cross-line noise attenuation is required alongside rapid post-power-down safety discharge. The integrated resistor eliminates the need for external parallel resistors, simplifying board layout. Verify that the 220 nF capacitance value aligns with the specific EMI filter design requirements and regulatory limits for leakage current.

Part Context

This part belongs to the KEMET P409 series of X2 safety capacitors designed for mains applications. The series utilizes metallized paper technology to provide reliable performance in high-voltage environments. The specific model integrates a discharge resistor, distinguishing it from standard passive safety capacitors within the same product family.

Replacement Considerations

Direct substitutes must match the 220 nF capacitance, 275 VAC rating, 20.3 mm lead spacing, and the integrated 33 Ω discharge resistor. Generic X2 capacitors without integrated resistors are not equivalent replacements unless external discharge circuitry is added.
