Procurement Notes

Verify the complete part number including the suffix TE01 to ensure correct packaging configuration. Confirm that the nickel barrier termination is compatible with your assembly process requirements. Cross-reference the manufacturer datasheet for specific reflow soldering profiles and moisture sensitivity level classifications prior to procurement.

Selection Notes

Select this component when space-constrained designs require superior high-frequency filtering performance. The 1806 footprint accommodates higher capacitance values than smaller packages while maintaining low parasitic inductance. Ensure the 50V rating exceeds the maximum circuit voltage with appropriate derating margins for reliability.

Part Context

This component belongs to the Knowles Syfer 1806J series of surface-mount feedthrough capacitors. The series utilizes advanced ceramic technologies to deliver consistent electrical characteristics. These parts are engineered for industrial and commercial applications demanding reliable EMI suppression in compact form factors.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 270pF capacitance, 50V rating, and three-terminal topology. Verify compatibility of termination materials and dielectric type to maintain circuit performance integrity.
