Overview
The Knowles Syfer SFJEC5000683MX1 is a feedthrough capacitor with a capacitance of 0.068 µF and a DC voltage rating of 500 VDC. It features an axial bushing configuration and supports a current rating of 15 A. The component utilizes X7R dielectric material, ensuring stability across an operating temperature range from -55°C to +125°C. Designed for EMI filtering, it offers high insulation resistance and robust performance in demanding electronic environments.
Feature Summary
- Provides effective electromagnetic interference (EMI) filtering through feedthrough architecture
- Supports high continuous current handling capabilities suitable for power applications
- Features axial bushing mounting for secure panel or chassis integration
Applications
- Power supply input filtering
- Industrial control system EMI suppression
- Medical equipment signal conditioning
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer before procurement. Confirm that the axial bushing dimensions match your mechanical design requirements. Ensure the 500V DC rating and 15A current capacity align with your circuit's operational limits. Check for any recent product change notices affecting electrical characteristics or packaging.
Selection Notes
Select this component when high-current EMI filtration is required in a compact axial form factor. The X7R dielectric provides stable capacitance over temperature variations. Consider the bushing mounting style for direct panel installation. Compare against other feedthrough options if surface mount solutions are preferred for automated assembly processes.
Part Context
This part belongs to the Knowles Syfer feedthrough capacitor family, designed for robust EMI suppression. These components integrate filtering functions directly into the mounting structure, reducing parasitic inductance compared to discrete capacitors. The series is engineered for reliability in industrial and medical applications requiring strict noise control.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching capacitance, voltage rating, current handling, and physical mounting dimensions before considering alternative components.
