Procurement Notes

Verify current availability status as this part may be obsolete or subject to long lead times. Confirm RoHS compliance details and specific packaging options such as cut tape or reel quantities directly with authorized distributors. Ensure the ordering suffix matches the required termination and tolerance specifications for your design.

Selection Notes

Select this component when space-constrained EMI filtering is required in automotive or industrial applications. The three-terminal design offers superior high-frequency attenuation compared to standard two-terminal capacitors. Verify that the 100V rating and 0.1µF capacitance align with the circuit's electrical requirements and thermal operating conditions.

Part Context

This component belongs to the KNH series of feed-through capacitors, which are specialized for noise suppression. Unlike standard MLCCs, these devices integrate a ground terminal to minimize parasitic inductance. The KNH21104-3AA specifically targets applications requiring robust EMI performance in small form factors, leveraging the KNH family's established reliability in automotive sectors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the three-terminal configuration, 0805 footprint, X7R dielectric, and 100V rating. Consult manufacturer databases for direct equivalents if this obsolete part is no longer sourced.
