Overview
The Knowles Syfer SFSWG5000680ZC0 is a flange-end seal feedthrough capacitor designed for EMI filtering. It features a 68 pF capacitance with a tolerance of -20% to +80%, rated for 500 VDC. The component utilizes C0G dielectric material and supports a current rating of 5 A. It operates within a temperature range of -55°C to +125°C and offers an insulation resistance of 10 GOhms. Physical dimensions include a length of 3.29 mm and a diameter of 3.25 mm, with solder termination.
Feature Summary
- Flange end seal construction for secure mounting
- C0G dielectric for stable performance
- High current handling capability
Applications
- EMI filtering in electronic circuits
- Feedthrough capacitor applications requiring flange mounting
Procurement Notes
Verify the specific capacitance tolerance (-20% to +80%) against circuit requirements, as it differs from standard symmetric tolerances. Confirm that the flange end seal package style matches the mechanical design constraints. Ensure the 500 VDC rating and 5 A current capacity are sufficient for the target application environment.
Selection Notes
Select this component when a flange-mounted feedthrough configuration is required for EMI suppression. The C0G dielectric ensures minimal capacitance variation over temperature and voltage. Consider the physical dimensions (3.29 mm x 3.25 mm) for panel cutout compatibility. Verify that the asymmetric tolerance range aligns with the system's noise filtering specifications.
Part Context
This part belongs to the SFSWG series of feedthrough capacitors from Knowles Syfer. The series is characterized by flange end seal packaging and is designed for high-reliability EMI filtering applications. Other parts in the series vary primarily in capacitance values while maintaining similar voltage ratings and physical form factors.
Replacement Considerations
Check for other SFSWG series parts with different capacitance values if the 68 pF value is not suitable. Verify that any substitute maintains the flange end seal package and 500 VDC rating.
