0805Y0250103MXTE07

Overview

The Knowles Syfer 0805Y0250103MXTE07 is a 0805 surface-mount multilayer ceramic capacitor with a capacitance of 10 nF, rated at 25 VDC. It utilizes X7R dielectric material and offers ±20% tolerance. The component features FlexiCap technology with nickel barrier and tin terminations for enhanced reliability. It functions as a three-terminal EMI filter feed-through capacitor, designed to suppress electromagnetic interference in compact electronic assemblies.

Feature Summary

• Integrates three-terminal EMI filtering capabilities within a standard surface-mount footprint
• Utilizes FlexiCap technology with flexible soft terminations to reduce mechanical stress on the substrate
• Employs nickel barrier termination structure to prevent electrode migration and enhance long-term stability

Applications

• Board-flex sensitive circuit designs requiring strain relief
• High-reliability electronics demanding EMI suppression
• Compact SMD/SMT assemblies needing integrated filtering

Procurement Notes

Verify the specific suffix MXTE07 against official Knowles Syfer documentation to confirm the presence of the nickel barrier termination and three-terminal EMI filter configuration. Ensure compatibility with RoHS3 standards and confirm that the FlexiCap feature meets the mechanical requirements of the target application before finalizing procurement.

Selection Notes

Select this component when board flex sensitivity is a critical design constraint due to its soft termination technology. Choose this part over standard MLCCs if integrated EMI filtering is required without increasing the component count. Verify that the 25V rating and 10nF capacitance align with the circuit's electrical specifications and thermal operating range.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in high-reliability capacitors with flexible terminations. The 0805Y series denotes the 0805 case size and X7R temperature coefficient. The specific model integrates EMI filtering functionality, distinguishing it from standard bypass capacitors by utilizing a three-terminal architecture for superior noise suppression.

Replacement Considerations

Direct substitutes must match the 0805 package, 10nF capacitance, 25V rating, X7R dielectric, and three-terminal EMI filter structure. Verify that any replacement also includes FlexiCap soft terminations and nickel barrier construction to maintain mechanical reliability and migration resistance in the original design.

FAQ

What is the primary function of the three-terminal design in this capacitor?

The three-terminal design enables the component to function as an integrated EMI filter, providing superior high-frequency noise suppression compared to standard two-terminal capacitors.

How does the FlexiCap technology benefit the circuit board?

FlexiCap technology uses flexible soft terminations that absorb mechanical stress, significantly reducing the risk of cracking or failure caused by board flexing during operation or assembly.
