P409CP224M275AH101

Overview

The KEMET P409CP224M275AH101 is a metallized paper film capacitor designed for X2 safety suppression applications. It features a capacitance of 220 nF with a ±20% tolerance and a rated AC voltage of 275 VAC, alongside a DC rating of 630 VDC. The component utilizes through-hole radial termination with a lead spacing of 20.3 mm. It operates within a temperature range of -40°C to +85°C and complies with EN/IEC 60384-14 standards.

Feature Summary

• X2 class safety certification for mains interference suppression
• Metallized paper dielectric with self-healing properties
• High dV/dt capability and resistance to transient voltages

Applications

• Cross-line noise suppression in AC power supplies
• EMI filtering in household appliances
• Industrial equipment power input stages

Procurement Notes

Verify the specific suffix AH101 corresponds to the required 20.3 mm lead spacing and bulk packaging configuration. Confirm RoHS compliance status and ensure the manufacturer part number matches the design specification exactly, as suffix variations may indicate different physical dimensions or termination styles.

Selection Notes

Select this component for circuits requiring X2 safety ratings across AC mains lines. Ensure the PCB layout accommodates the 20.3 mm lead pitch and the physical envelope dimensions. Verify that the operating voltage does not exceed the 275 VAC rating under all expected line conditions.

Part Context

This part belongs to the KEMET P409 series of metallized paper capacitors. The series is engineered for high-reliability safety applications where failure must not create shock hazards. The P409 designation indicates the specific form factor and electrical characteristics defined by the manufacturer for cross-line filtering.

Replacement Considerations

Substitutes must match the 220 nF capacitance, 275 VAC rating, X2 safety classification, and 20.3 mm lead spacing. Verify that alternative components meet identical regulatory approvals (UL, EN/IEC) and physical footprint constraints.
