Overview
The Knowles Syfer 0805Y0250123MXTE07 is a 0.012 µF (12 nF) feed-through capacitor rated for 25V DC with a 1A current rating. It utilizes an X7R dielectric in a 0805 (2012 metric) surface-mount package. The component features a three-terminal EMI filter design with nickel barrier and 100% tin terminations, ensuring robust performance in high-frequency noise suppression applications.
Feature Summary
- Three-terminal EMI filter architecture for enhanced noise attenuation
- Feed-through capacitor design integrating filtering within the package
- Nickel barrier termination system for improved solderability and reliability
Applications
- High-frequency noise suppression in sensitive electronic circuits
- EMI filtering in compact surface-mount assemblies
- Signal integrity protection in communication modules
Procurement Notes
Verify the specific MXTE07 suffix against official Knowles Syfer documentation to confirm terminal composition and RoHS compliance status. Ensure the selected variant matches the required nickel barrier specification for your assembly process. Cross-reference the datasheet for exact dimensional tolerances and recommended reflow profiles prior to integration.
Selection Notes
Select this component when board space constraints require a 0805 footprint but higher filtering efficiency than standard two-terminal MLCCs. The three-terminal structure provides superior common-mode noise rejection compared to conventional capacitors. Consider the 1A current rating and 25V DC voltage limit during circuit design to ensure adequate headroom for operational conditions.
Part Context
This part belongs to the Knowles Syfer FlexiCap™ series of multilayer ceramic capacitors. It is specifically engineered as an EMI filter rather than a standard energy storage capacitor. The product line emphasizes reliability in harsh environments through specialized termination technologies and stable X7R dielectric characteristics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing footprints if considering alternative manufacturers, noting that three-terminal EMI filter geometries may differ from standard MLCC packages.
