Procurement Notes
Verify the specific suffix and manufacturer part number against official Knowles Syfer documentation to ensure correct dielectric type and terminal configuration. Confirm RoHS compliance status and packaging options such as cut tape or reel availability through authorized distributors before procurement.
Selection Notes
Select this component when high stability and low loss are required for EMI filtering in compact designs. The 1806 footprint offers a balance between current handling capability and board space efficiency compared to smaller packages, suitable for applications requiring robust noise suppression without excessive size.
Part Context
This component belongs to the Knowles Syfer E01 series of surface-mount EMI filters. These capacitors are engineered to provide superior attenuation performance compared to standard two-terminal MLCCs by utilizing a third ground terminal to shunt common-mode noise effectively to the chassis or ground plane.
