Procurement Notes

Verify the specific suffix TE01 against official datasheets to confirm packaging configuration and terminal specifications. Ensure compatibility with standard SMD reflow processes. Confirm RoHS compliance status through current manufacturer documentation before integration into production lines.

Selection Notes

Select this component when space-constrained designs require robust EMI filtering in the 1806 footprint. The combination of X7R dielectric and FlexiCap terminations makes it suitable for environments subject to mechanical stress or significant thermal variations without compromising electrical integrity.

Part Context

This part belongs to the Knowles Syfer FlexiCap MLCC series, engineered for superior mechanical resilience compared to conventional capacitors. The series is recognized for its ability to withstand board bending and extensive thermal cycling, making it a preferred choice for aerospace and high-reliability industrial applications requiring durable surface-mount solutions.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 56 nF capacitance, 50V rating, and three-terminal EMI filter structure. Verify that alternative components also feature compatible termination technologies if mechanical reliability is critical.
