P409CE104M275AH330

Overview

The KEMET P409CE104M275AH330 is a metallized paper film capacitor designed for EMI suppression. It features a capacitance of 100 nF with a tolerance of ±20%. The component is rated for 275 VAC and 630 VDC, classifying it as an X2 safety capacitor. It utilizes a radial through-hole termination with a lead spacing of 20.3 mm. An integrated series resistor of 33 Ohms is included within the package. The unit operates within a temperature range of -40°C to +85°C and complies with EN/IEC 60384-14 standards.

Feature Summary

• Integrates a 33 Ohm series resistor for RC snubber applications
• X2 safety classification for mains interference suppression
• Metallized paper dielectric construction
• Radial leaded package for through-hole mounting

Applications

• RC low-pass filter networks in power supplies
• EMI suppression across AC mains inputs
• Motor drive interference filtering
• General purpose noise reduction in electronic equipment

Procurement Notes

Verify the specific suffix AH330 confirms the 33 Ohm internal resistance value, as this distinguishes it from standard capacitors in the same voltage and capacitance range. 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 RC network is required for first-order low-pass filtering without additional discrete resistors. The X2 rating ensures safety compliance for direct connection to AC mains lines. Consider the physical dimensions and thermal limits relative to the enclosure design. Verify that the 100 nF capacitance value meets the specific cutoff frequency requirements of the application circuit.

Part Context

This part belongs to the KEMET P409 series, which specializes in metallized paper film capacitors with built-in resistors. These components are engineered specifically for EMI/RFI suppression tasks where space efficiency and simplified assembly are priorities. The series combines passive filtering elements into a single standardized package, reducing board space compared to discrete component arrangements.

Replacement Considerations

Direct substitutes must match the 100 nF capacitance, 275 VAC rating, 33 Ohm internal resistance, and 20.3 mm lead pitch. Verify equivalent X2 safety certifications and operating temperature ranges. Cross-reference pinout and physical dimensions to ensure mechanical compatibility during replacement.
