SFJEL5000224MX1

Overview

The Knowles Syfer SFJEL5000224MX1 is an EMI feedthrough filter capacitor with a capacitance of 0.22 µF and a DC voltage rating of 500 VDC. It utilizes X7R dielectric material and offers a tolerance of ±20%. Designed for axial lead termination, this component supports a maximum DC current of 5 A. The unit operates within a temperature range of -55°C to +125°C and features a flange end seal construction.

Feature Summary

• Provides electromagnetic interference suppression through high-capacitance feedthrough design
• Features robust axial lead termination for secure panel or chassis mounting
• Utilizes X7R ceramic dielectric for stable performance across wide temperature ranges

Applications

• Power supply input filtering in industrial control systems
• EMI suppression in aerospace avionics power distribution networks
• Signal integrity protection in military communication equipment
• Noise reduction in medical device power interfaces

Procurement Notes

Verify the specific suffix MX1 against the manufacturer's latest datasheet to confirm exact mechanical dimensions and termination plating specifications. Confirm RoHS compliance status directly with Knowles Syfer documentation prior to integration. Ensure thermal management strategies align with the 125°C maximum operating temperature limit defined in the official component specifications.

Selection Notes

Select this component when high capacitance values are required in a compact axial form factor for EMI filtering applications. The 500V rating makes it suitable for medium-voltage DC bus filtering. Compare against the SFSWG series if surface mount solutions are preferred, noting that the SFJE series offers distinct mechanical mounting advantages for threaded or direct wire connections in constrained spaces.

Part Context

This part belongs to the SFJE series of feedthrough capacitors from Knowles Syfer. The series is characterized by its ability to handle significant ripple currents while maintaining low impedance at high frequencies. These components are engineered for reliability in harsh environments, distinguishing them from standard discrete capacitors used in general consumer electronics.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Engineers should consult the official Knowles Syfer replacement guide or contact the manufacturer directly for qualified alternatives that match the 0.22 µF, 500 VDC, and axial lead specifications.
