P409CP104M275AH151

Overview

The KEMET P409CP104M275AH151 is a paper dielectric film capacitor designed for X2 safety suppression applications. It features a capacitance of 100 nF with a tolerance of ±20%. The component is rated for 275 VAC at 50/60 Hz and 275 VDC. It utilizes a radial through-hole mounting configuration with a lead spacing of 20.3 mm. The unit operates within a temperature range of -40°C to +85°C and includes an integrated series resistor of 150 Ω.

Feature Summary

• Incorporates an internal series resistor for RC snubber functionality
• Certified for X2 safety class across multiple international standards
• Utilizes metallized paper dielectric for high voltage stability

Applications

• Motor run and start circuits
• Power supply input filtering
• RC snubber networks in switching applications

Procurement Notes

Verify the specific suffix AH151 to confirm the inclusion of the 150 Ohm internal 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 via the manufacturer's current documentation before finalizing procurement specifications.

Selection Notes

Select this component when an integrated damping resistor is required for noise suppression or voltage spike protection. The 100 nF value and 275 VAC rating are suitable for general mains interference suppression. Verify that the physical dimensions fit the assembly constraints and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the KEMET P409 series of safety capacitors. These components are engineered for electromagnetic interference (EMI) suppression in AC power line applications. The series is widely used in industrial equipment and consumer electronics to meet regulatory emissions standards while providing reliable circuit protection.

Replacement Considerations

Direct substitutes must match the 100 nF capacitance, 275 VAC rating, 20.3 mm pitch, and 150 Ohm internal resistance. Cross-reference with other manufacturers' X2 paper capacitors featuring integrated resistors to ensure equivalent electrical and mechanical compatibility.
