P410CJ473M300AH101

Overview

The KEMET P410CJ473M300AH101 is a radial leaded film capacitor designed for AC line suppression applications. It features a metallized paper dielectric with a capacitance of 47 nF and a tolerance of ±20%. The component is rated for 300 VAC and 300 VDC, ensuring safety compliance as an X1 class suppression capacitor. It utilizes a through-hole mounting configuration with a standard 20.3 mm lead pitch. The unit operates within a temperature range up to 85°C and meets international safety standards including EN/IEC 60384-14, UL 60384-14, and CAN/CSA-E60384-14-09.

Feature Summary

• X1 class safety certification for AC line interference suppression
• Metallized paper dielectric construction for high reliability
• Through-hole axial lead design with 20.3 mm spacing

Applications

• AC mains input filtering in consumer electronics
• EMI suppression in industrial power supplies
• Safety-critical circuit protection in household appliances

Procurement Notes

Verify the specific manufacturing date code and batch lot against project requirements, as this component type may have varying production statuses across different regions. Confirm that the X1 safety rating aligns with local regulatory mandates for the intended end-use equipment. Ensure that the physical dimensions and lead pitch match the PCB footprint specifications to prevent assembly errors during installation.

Selection Notes

Select this component when designing circuits requiring certified AC line suppression with moderate capacitance values. The X1 rating indicates suitability for direct connection to the AC mains, providing protection against transient overvoltages. Consider the paper dielectric characteristics regarding long-term stability and leakage current compared to polypropylene alternatives. Evaluate the thermal limitations of the 85°C maximum operating temperature against the ambient conditions of the final enclosure.

Part Context

This part belongs to the KEMET P410 series, which specializes in paper-based film capacitors for general-purpose AC suppression. The series is characterized by its robust safety certifications and cost-effective construction using metallized paper. These components are widely utilized in applications where space constraints are less critical than cost and proven safety performance, serving as a standard solution for basic EMI filtering on AC lines.

Replacement Considerations

Direct substitutes must maintain the 47 nF capacitance, 300 VAC/VDC ratings, and X1 safety classification. Verify that alternative parts offer identical lead pitch and mechanical dimensions for board compatibility. Ensure replacement components hold equivalent international safety approvals (UL, EN/IEC) to maintain compliance with the original equipment design specifications.
