P409CP224M275AH151

Overview

The KEMET P409CP224M275AH151 is a metallized paper film capacitor with an integrated series resistor, designed for X2 safety suppression. It features a capacitance of 220 nF and a resistance value of 150 Ohms. The component is rated for 275 VAC and 630 VDC, operating within a temperature range of -40°C to +85°C. It utilizes a radial through-hole package with a lead spacing of 20.3 mm and a tolerance of ±20%. Certified under EN/IEC 60384-14, UL 60384-14, and CAN/CSA-E60384-14-09 standards.

Feature Summary

• Integrates a 150 Ohm resistor in series with the capacitor element for RC snubber applications
• Constructed with metallized paper dielectric for high reliability in AC line filtering
• Complies with international safety standards for X2 class interference suppression capacitors

Applications

• RC snubber circuits in power electronics
• Electromagnetic interference (EMI) suppression in AC mains inputs
• Safety-critical filtering in household appliances and industrial equipment

Procurement Notes

Verify the specific suffix AH151 confirms the 150 Ohm internal resistance value, as this variant differs from standard P409 capacitors without resistors. Ensure the ordering documentation explicitly references the integrated resistor specification to avoid confusion with passive-only components in the same series.

Selection Notes

Select this component when both EMI suppression and voltage spike damping are required in a single footprint. The integrated resistor eliminates the need for external discrete components, simplifying PCB layout. Confirm that the 150 Ohm resistance value aligns with the circuit's snubber design requirements for optimal performance.

Part Context

This part belongs to the KEMET P409 series of safety capacitors. Unlike standard X2 capacitors, this specific model includes an internal resistor, categorizing it as an RC snubber or filter component. It shares the physical dimensions and safety certifications of the broader P409 family but offers enhanced functionality for transient suppression.

Replacement Considerations

Direct substitutes must match the 220 nF capacitance, 150 Ohm resistance, and 20.3 mm lead spacing. Verify that any replacement also carries X2 safety ratings and identical certification marks (UL, EN/IEC, CSA) to maintain compliance in end-product designs.
