P409EL474M275AH221

Overview

The KEMET P409EL474M275AH221 is a metallized paper film capacitor designed for safety applications. It features a capacitance of 470 nF with a tolerance of ±20%. The component is rated for 275 VAC and 275 VDC, classifying it as an X2 suppression type. It utilizes through-hole radial mounting with a lead spacing of 25.4 mm. The unit operates within a temperature range of -40°C to +85°C and holds certifications including UL, EN/IEC, and CSA standards.

Feature Summary

• X2 safety classification for electromagnetic interference suppression
• Metallized paper dielectric construction
• Radial through-hole termination style
• Compliance with international safety standards

Applications

• Cross-line noise suppression in AC power supplies
• EMI filtering in household appliances
• Industrial control equipment input stages
• Lighting ballast circuits

Procurement Notes

Verify the specific suffix AH221 against official KEMET documentation to confirm lead length and packaging details. Ensure the procurement channel provides valid certification copies for UL and IEC compliance. Confirm that the delivered units match the specified 25.4 mm lead spacing and 470 nF capacitance value before integration into production lines.

Selection Notes

Select this component when designing circuits requiring X2 safety ratings for AC line filtering. The 275 VAC rating suits regions with standard mains voltages. Consider the 85°C maximum operating temperature limit for thermal management. The 25.4 mm pitch requires compatible PCB hole patterns or wire-wrapped connections.

Part Context

This part belongs to the KEMET P409 series of safety capacitors. The series is characterized by metallized paper technology and robust surge withstand capabilities. It serves as a standard solution for cross-line applications where failure must not create shock hazards. The model number encodes the capacitance, voltage, and physical dimensions.

Replacement Considerations

Direct substitutes include other X2 capacitors with identical 470 nF capacitance, 275 VAC rating, and 25.4 mm lead spacing. Verify that any replacement also carries UL, EN/IEC, and CSA approvals for the same application class.
