Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's latest datasheet before procurement. Confirm that the hex head dimensions and thread specifications match the mechanical constraints of the target enclosure. Ensure compliance with RoHS directives if required by the final assembly standards. Cross-reference the lead time requirements with production schedules due to potential supply chain variability for specialized feedthrough components.

Selection Notes

Select this component when high-voltage DC filtering is required in space-constrained panels. The axial feedthrough design allows direct integration into chassis holes, eliminating the need for additional wiring harnesses. Consider the 500V rating and 6800pF capacitance for effective high-frequency noise attenuation. Verify thermal management capabilities given the operating temperature limits and self-heating characteristics under load conditions.

Part Context

This part belongs to the Knowles Syfer SFAKC series of EMI feedthrough filters. These components are engineered for harsh environments requiring reliable noise suppression. The series offers various capacitance values and voltage ratings to suit different circuit protection needs. They are commonly used in military, aerospace, and industrial applications where electromagnetic interference must be strictly controlled.

Replacement Considerations

Direct replacements require matching the 6800pF capacitance, 500V rating, and M3.5 hex head mounting interface. Verify that alternative feedthrough capacitors maintain similar X7R dielectric properties and physical footprint dimensions to ensure compatibility with existing PCB layouts and panel cutouts.
