SFCDC5000223MX0

Overview

The Knowles Syfer SFCDC5000223MX0 is an EMI feedthrough filter capacitor designed for high-voltage applications. It features a capacitance of 22 nF with a tolerance of 20% and a DC voltage rating of 500 VDC. The component utilizes X7R dielectric material, ensuring stable performance across a temperature range of -55°C to +125°C. It supports a maximum DC current of 10 A and employs a C-filter circuit topology. The physical construction includes a 6.35 mm diameter body with 0.7 mm lead wires and 12-32 thread sizing.

Feature Summary

• Provides effective electromagnetic interference suppression through integrated feedthrough filtering architecture
• Supports high direct current loads up to 10 amperes without degradation
• Maintains electrical stability under extreme thermal conditions ranging from negative fifty-five to positive one hundred twenty-five degrees Celsius

Applications

• High-voltage power supply input filtering
• Industrial control system noise reduction
• Medical equipment signal integrity protection

Procurement Notes

Verify the specific thread size designation matches the mounting hardware requirements before integration. Confirm that the 10 A current rating aligns with the operational load profile of the target circuit. Ensure the 500 VDC rating exceeds the peak operating voltage to prevent dielectric breakdown. Check for any RoHS compliance documentation updates relevant to the manufacturing batch.

Selection Notes

Select this component when high-current handling capability is required alongside significant EMI attenuation in compact axial configurations. The X7R dielectric offers a balance between capacitance density and temperature stability suitable for general industrial environments. Consider the 12-32 threading standard to ensure compatibility with existing panel cutouts and nut assemblies.
