Procurement Notes

Verify the specific suffix designation against official manufacturer documentation, as variations may exist between MC0 and MC1 designations. Confirm current product status, as some sources indicate this model may be obsolete or restricted. Ensure compatibility with required panel thickness and mounting hardware specifications before procurement.

Selection Notes

Select this component when high-voltage isolation and low-capacitance filtering are required. The 100 pF value suits high-frequency noise attenuation. Verify that the 3 kV rating exceeds peak circuit voltages. Consider the physical dimensions for enclosure integration. Ensure the 15 A current capacity meets load requirements without thermal degradation.

Part Context

This component belongs to the Knowles Syfer feedthrough capacitor series, specialized for harsh environment reliability. These devices integrate capacitive elements directly into conductive housings, providing superior shielding compared to standard MLCCs. The series targets industries demanding stringent electromagnetic compatibility and long-term operational stability under extreme conditions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Cross-reference with other Knowles Syfer feedthrough models only if electrical parameters and mechanical dimensions match exactly. Consult manufacturer engineering support for qualified alternatives.
