Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to confirm specific termination and packaging configurations. Ensure that the requested variant matches the required electrical specifications and physical dimensions for your design. Cross-reference datasheets to validate compliance with relevant environmental standards before finalizing procurement orders.

Selection Notes

Select this component when a compact three-terminal EMI filter is required within an 1806 footprint. The X7R dielectric offers a balance of high volumetric efficiency and temperature stability suitable for general-purpose applications. Consider the nickel barrier construction if lead-free soldering processes are mandated by regulatory requirements or assembly constraints.

Part Context

This component belongs to the Knowles Syfer MLCC portfolio, specifically engineered for surface mount applications. The 1806 case size allows for dense PCB layouts while maintaining adequate power handling. As a three-terminal device, it differs from standard two-terminal capacitors by providing superior high-frequency noise attenuation through its grounded center terminal configuration.

Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements may not match the three-terminal EMI filtering topology or the specific nickel barrier termination properties.
