0805Y1000123MXTE01

Overview

The Knowles Syfer 0805Y1000123MXTE01 is a pass-through feed-through capacitor designed for surface mount applications. It features a capacitance of 12,000 pF (0.012 µF) with a voltage rating of 100 VDC and a tolerance of ±20%. The component utilizes an X7R dielectric material and operates within a temperature range of -55°C to +125°C. Housed in a standard 0805 (2012 metric) package, it incorporates flexible termination technology to enhance mechanical reliability under board flex conditions.

Feature Summary

• Pass-through feed-through architecture providing integrated EMI filtering capabilities
• Flexible termination design engineered to withstand significant board bending stress
• X7R dielectric composition ensuring stable performance across the specified operating temperature range

Applications

• Boardflex sensitive circuit assemblies requiring enhanced mechanical durability
• High-density surface mount layouts demanding integrated filtering solutions
• Automotive electronic systems subject to rigorous vibration and thermal cycling standards

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm terminal configuration and electrical characteristics. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference part numbers carefully as minor variations may indicate different termination materials or voltage ratings.

Selection Notes

Select this component when space constraints require a combined decoupling and filtering function in a compact footprint. The flexible termination feature makes it suitable for rigid-flex boards or applications prone to mechanical stress. Confirm that the X7R temperature coefficient aligns with the stability requirements of the target circuit application.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in multilayer ceramic capacitors with proprietary flexible terminations. The series is engineered to improve reliability in harsh environments by accommodating mechanical strain that typically causes conventional MLCCs to crack. The feed-through variant integrates filtering directly into the mounting structure.

Replacement Considerations

Direct substitutes must match the 0805 pass-through form factor and 100V rating. Verify that alternative components offer comparable flexible termination properties to maintain mechanical integrity in boardflex-sensitive designs.
