P409QM473M275AH101

Overview

The KEMET P409QM473M275AH101 is a metallized paper film capacitor designed for X2 EMI suppression applications. It features a capacitance of 47 nF with a tolerance of ±20%. The component is rated for 275 VAC and 275 VDC, ensuring safety compliance in mains-connected circuits. It utilizes a radial through-hole package with a 15.2 mm lead pitch and straight leads. The unit operates within a temperature range of -40°C to +85°C and measures 18.5 mm in length, 7.3 mm in depth, and 13 mm in height.

Feature Summary

• X2 class safety certification for mains interference suppression
• Metallized paper dielectric construction
• Radial through-hole mounting configuration

Applications

• EMI/RFI filtering in AC power line inputs
• Cross-line noise suppression in household appliances
• Safety capacitors in industrial control equipment

Procurement Notes

Verify the specific suffix AH101 against official KEMET documentation to confirm lead pitch and termination details. Ensure the application environment remains within the specified -40°C to +85°C operating range. Confirm that the 275V AC rating aligns with local mains voltage standards and regulatory requirements for X2 safety capacitors before integration.

Selection Notes

Select this component when an X2-rated safety capacitor is required for cross-line filtering in AC mains applications. The 47 nF value and 15.2 mm pitch are suitable for standard PCB layouts requiring moderate capacitance in compact spaces. Consider the metallized paper dielectric for cost-effective noise suppression where high-frequency performance is secondary to basic EMI reduction.

Part Context

This part belongs to the KEMET P409 series, which comprises X2 safety capacitors utilizing metallized paper technology. These components are engineered for reliability in suppressing electromagnetic interference across AC power lines. The series adheres to international safety standards including IEC 60384-14 and UL 60384-14, making them suitable for global electronic product certifications.

Replacement Considerations

Direct substitutes must match the 47 nF capacitance, 275 VAC rating, X2 safety class, and 15.2 mm lead pitch. Verify that alternative manufacturers offer equivalent metallized paper construction and identical physical dimensions for board compatibility.
