P410QS333M300AH101

Overview

The KEMET P410QS333M300AH101 is a metallized paper safety capacitor belonging to the P410 series, designed for X1 class EMI suppression. It features a capacitance of 33 nF with a tolerance of ±20%. The component is rated for 300 VAC and 1 kVDC. It utilizes radial through-hole mounting with a lead spacing of 15.2 mm and straight leads of 0.8 mm diameter. The physical dimensions are 18.5 mm in length, 8.5 mm in width, and 14.3 mm in height. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• X1 class safety certification for mains interference suppression
• Metallized paper dielectric construction
• Radial through-hole termination for standard PCB mounting

Applications

• EMI/RFI filtering in AC power input stages
• Cross-line noise suppression in household appliances
• Industrial equipment power supply circuits

Procurement Notes

Verify the specific suffix AH101 against the manufacturer datasheet to confirm lead configuration and packaging details. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range. Confirm that the 300 VAC rating aligns with the local mains voltage standards where the component will be deployed.

Selection Notes

Select this component when X1 safety ratings and metallized paper dielectrics are required for cross-line applications. Compare lead spacing options if board layout constraints differ from the standard 15.2 mm pitch. Consider thermal derating requirements if operation approaches the maximum temperature limit of 85°C.

Part Context

This part belongs to the KEMET P410 series of suppression film capacitors. The series offers various capacitance values and lead spacings to accommodate different circuit board layouts. These components are engineered for reliability in high-voltage AC environments, providing robust performance for electromagnetic interference mitigation in electronic devices.

Replacement Considerations

Direct substitutes must match the 33 nF capacitance, 300 VAC rating, X1 classification, and 15.2 mm lead spacing. Verify equivalent safety approvals such as UL or ENEC. Metallized paper technology should be maintained for similar electrical characteristics.
