Procurement Notes
Verify the exact part number against official manufacturer documentation to confirm the MXTE01 suffix specifications. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference datasheets for electrical characteristics such as impedance and current ratings before finalizing procurement decisions.
Selection Notes
Select this component when space-constrained EMI filtering is required without breaking the signal path. The 0805 package offers a balance between capacitance density and board area. Consider the X7R temperature coefficient for environments with significant thermal fluctuations.
Part Context
This component belongs to the Knowles Syfer MLCC family, specifically designed for high-reliability applications. The brand is known for specialized capacitors used in demanding industries. This specific model integrates filtering capabilities directly into the capacitor structure, distinguishing it from standard multilayer ceramic capacitors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify pinout and electrical parameters carefully if considering alternative manufacturers or series.
