SFSWR5000330ZC0

Overview

The Knowles Syfer SFSWR5000330ZC0 is a feedthrough capacitor designed for EMI filtering applications. It features a capacitance of 33 pF with a tolerance range of -20% to +80%. The component has a DC voltage rating of 500 VDC and supports a maximum current of 5 A. Constructed with C0G dielectric, it operates within a temperature range of -55°C to +125°C. The unit utilizes solder termination and has a bottom end seal configuration. Physical dimensions include a length of 3.29 mm and a diameter of 3.25 mm, with an insulation resistance of 10 GOhms.

Feature Summary

• Provides electromagnetic interference (EMI) filtering through a single-terminal C-filter topology.
• Utilizes C0G dielectric material for stable electrical performance across the operating temperature range.
• Features a bottom end seal construction for secure mounting and environmental protection.

Applications

• High-frequency signal line filtering in electronic circuits
• Power supply input/output noise suppression
• Electromagnetic compatibility (EMC) improvement in sensitive equipment

Procurement Notes

Verify the specific suffix ZC0 against official datasheets to confirm the bottom end seal configuration and tolerance specifications. Ensure that the 500 VDC rating and 5 A current capacity align with the target circuit requirements. Confirm RoHS compliance status through manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when a compact, high-voltage feedthrough capacitor is required for EMI suppression. The C0G dielectric ensures minimal capacitance variation with temperature and voltage. The bottom end seal design offers mechanical stability for panel-mount or chassis-mount installations where space is constrained.

Part Context

This part belongs to the SFSWR series of feedthrough capacitors from Knowles Syfer. The series is characterized by its small form factor and high reliability for industrial and commercial applications. The SFSWR designation specifically indicates the bottom end seal variant within the broader product family.

Replacement Considerations

Consult official substitution guides for compatible parts. Verify that any alternative maintains the same voltage rating, capacitance value, and physical footprint to ensure proper fit and function in existing designs.
