SFJEC5000224MX0

Overview

The SFJEC5000224MX0 is a feedthrough capacitor manufactured by Knowles Syfer, designed for electromagnetic interference (EMI) filtering. It features a capacitance of 0.22 µF with a DC voltage rating of 500 VDC and a current rating of 15 A. The component utilizes an axial bushing configuration for mounting. It employs X7R dielectric material to ensure stable performance across a wide temperature range from -55°C to +125°C. The device provides effective noise suppression in high-voltage power applications.

Feature Summary

• Axial bushing design facilitates direct panel or chassis mounting for secure grounding.
• High current handling capability supports demanding power line environments.
• X7R ceramic dielectric offers reliable capacitance stability under varying thermal conditions.

Applications

• Power supply input filtering
• Industrial control system EMI suppression
• Medical equipment power lines

Procurement Notes

Verify the specific axial bushing dimensions against your chassis hole specifications before integration. Confirm that the 15 A current rating aligns with your circuit's maximum load requirements. Ensure the 500 VDC rating exceeds the peak operating voltage of the application. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a robust, through-hole mounting solution is preferred over surface mount alternatives. The axial form factor simplifies installation in enclosed spaces where board space is limited but panel penetration is available. Consider the physical size constraints of the bushing interface during mechanical design.

Part Context

This part belongs to the Knowles Syfer feedthrough capacitor portfolio, which specializes in high-reliability EMI filters. These components are engineered for harsh environments requiring superior noise attenuation compared to standard capacitors. The series is commonly used in aerospace, defense, and industrial sectors where signal integrity is critical.

Replacement Considerations

Direct substitutes must match the 0.22 µF capacitance, 500 VDC rating, 15 A current capacity, and axial bushing package. Verify pin spacing and overall length compatibility. Alternative brands may offer similar specifications but require mechanical fit verification.
