P409EL474M275AH101

Overview

The KEMET P409EL474M275AH101 is a metallized paper film capacitor with an integrated series resistor, designed for EMI suppression. It features a capacitance of 0.47 µF (470 nF) with a ±20% tolerance and a rated AC voltage of 275 VAC at 50/60 Hz. The component includes a built-in discharge resistor of 100 Ω. It utilizes through-hole radial mounting with a lead spacing of 25.4 mm. The unit operates within a temperature range of -40°C to +85°C and complies with EN/IEC 60384-14 standards for X2 class safety capacitors.

Feature Summary

• Integrates a 100 Ω series resistor for effective electromagnetic interference suppression
• Constructed with metallized paper dielectric for high reliability in AC applications
• Certified as an X2 safety capacitor compliant with international standards

Applications

• Power supply input filtering
• Motor drive circuits
• General purpose EMI suppression

Procurement Notes

Verify the specific suffix AH101 to confirm the 100 Ω resistance value, as other suffixes indicate different resistances. Ensure the 25.4 mm lead pitch matches the target PCB footprint. Confirm RoHS compliance status if required by local regulations. Cross-reference the manufacturer part number against official distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a combined RC snubber or filter is required in a single package. The 0.47 µF capacitance and 100 Ω resistance are optimized for standard mains frequency noise attenuation. Consider the physical dimensions of 30.5 mm length and 22 mm height for enclosure clearance. The 275 VAC rating provides sufficient margin for most global mains voltages.

Part Context

This part belongs to the KEMET P409 series of safety capacitors. The series offers various capacitance values ranging from 0.047 µF to 0.47 µF. Different suffixes denote varying resistance values, such as 22 Ω, 47 Ω, or 470 Ω. All variants share the same X2 safety classification and metallized paper construction.

Replacement Considerations

Compatible substitutes include KEMET P409EL474M275AH220 (22 Ω), P409EL474M275AH470 (470 Ω), and P409QM473M275AH101 (47 nF, 100 Ω). Verify that any replacement maintains the 25.4 mm lead spacing and 275 VAC rating.
