0805Y0250681MXTE01

Overview

The Knowles Syfer 0805Y0250681MXTE01 is a feed-through ceramic capacitor designed for surface-mount applications. It features a capacitance of 680 pF with a DC voltage rating of 25 V and a current rating of 300 mA. 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 employs a three-pad configuration to facilitate high-frequency signal filtering and power line decoupling in compact electronic designs.

Feature Summary

• Integrates feed-through architecture for effective electromagnetic interference suppression
• Utilizes X7R dielectric for stable capacitance across wide temperature variations
• Features a three-pad surface-mount footprint for enhanced mechanical stability

Applications

• High-frequency signal filtering in communication circuits
• Power line decoupling for sensitive integrated circuits
• Electromagnetic interference suppression in compact modules

Procurement Notes

Verify the specific suffix MXTE01 against official datasheets to confirm the three-pad terminal configuration and current rating. Ensure compatibility with PCB footprints designed for feed-through capacitors rather than standard MLCCs. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Selection Notes

Select this component when board space is limited but high-frequency noise suppression is critical. The 0805 form factor allows for dense layouts. Verify that the 300 mA current handling meets circuit requirements. Consider the three-terminal design for superior RF performance compared to two-terminal alternatives in similar packages.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, distinct from standard multilayer ceramic capacitors. These components are engineered specifically for EMI/RFI filtering applications where high current handling and low impedance at high frequencies are required. The 0805 size offers a balance between performance and miniaturization.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Consult manufacturer cross-reference tools or equivalent feed-through capacitor specifications from other vendors if direct substitution is necessary.
