The component has a DC voltage rating of 500 VDC and utilizes C0G dielectric material. It supports a current rating of 5 A and operates within a temperature range of -55°C to +125°C. The unit employs 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 filtering through a C-filter topology.
• Utilizes C0G dielectric for stable electrical performance across the operating temperature range.
• Features a bottom end seal construction for secure mounting.

Applications

• EMI filtering in electronic circuits
• Power supply line conditioning
• Signal path noise suppression

Procurement Notes

Verify the specific suffix ZC0 corresponds to the bottom end seal configuration required for your assembly. Confirm that the -20% to +80% tolerance aligns with circuit design specifications. Ensure the 500 VDC rating meets system voltage requirements. Check lead times as production cycles may vary. Validate RoHS compliance status through official manufacturer documentation before integration.

Selection Notes

Select this component when a compact C-filter topology is needed for high-frequency noise attenuation. The C0G dielectric ensures minimal capacitance drift over temperature variations compared to other classes. The 5 A current rating supports moderate power line applications. Consider the physical footprint of 3.29 mm length and 3.25 mm diameter for board space constraints. Verify compatibility with soldering processes suitable for feedthrough capacitors.

Part Context

This part belongs to the SFSWR series of feedthrough capacitors from Knowles Syfer. The series offers various capacitance values and voltage ratings within a standardized small form factor. These components are categorized under EMI filters and are designed for robust performance in demanding environments. The SFSWR designation indicates specific sealing and terminal characteristics distinct from other series like SFSWG.

Replacement Considerations

Direct substitutes must match the 22 pF capacitance, 500 VDC rating, C0G dielectric, and bottom end seal configuration. Verify identical physical dimensions (3.29 mm x 3.25 mm) and 5 A current rating. Ensure the replacement part maintains the same -20% to +80% tolerance and operating temperature range. Cross-reference termination type and sealing method to guarantee mechanical and electrical compatibility.
