SFJEL5000103MX0

Overview

The Knowles Syfer SFJEL5000103MX0 is an EMI feedthrough capacitor with a capacitance of 10 nF and a voltage rating of 500 VDC. It utilizes X7R dielectric material with a tolerance of ±20%. The component supports a maximum DC current of 15 A and operates within a temperature range of -55°C to +125°C. Physical dimensions are 9.8 mm in diameter and 9.4 mm in length, featuring axial bushing mounting.

Feature Summary

• Provides electromagnetic interference suppression through feedthrough filtering architecture
• Supports high continuous direct current loads up to 15 amperes
• Utilizes X7R ceramic dielectric for stable performance across wide temperature variations

Applications

• Electromagnetic interference filtering in electronic enclosures
• Power supply input/output conditioning
• High-current signal line protection

Procurement Notes

Verify component status as the source indicates this part may be obsolete. Confirm availability through authorized distributors or secondary markets if active procurement is required. Ensure the axial bushing mounting style matches the mechanical design constraints of the target application panel.

Selection Notes

Select this component when high current handling capacity of 15 A is required alongside 500 VDC isolation. The axial bushing form factor necessitates panel cutout compatibility. Verify that the 10 nF capacitance value provides sufficient attenuation for the specific noise frequencies present in the circuit environment.

Part Context

This component belongs to the Knowles Syfer feedthrough capacitor series, designed for robust EMI suppression in demanding environments. It represents a specialized passive filter solution distinct from standard surface mount or through-hole capacitors due to its integrated grounding path and high current capability.

Replacement Considerations

Check for updated series replacements from Knowles Syfer if active sourcing is needed. Cross-reference other manufacturers offering 10 nF, 500 VDC, 15 A axial feedthrough capacitors with compatible physical dimensions and X7R characteristics.
