0805Y0250223MXTE01

Overview

The Knowles Syfer 0805Y0250223MXTE01 is a multilayer ceramic capacitor (MLCC) designed for surface mount applications. It features a capacitance of 22.00 nF with a tolerance of ±20% and utilizes X7R dielectric material. The component is rated for a DC voltage of 25V and operates within a temperature range of -55°C to +125°C. It employs a FlexiCap™ technology with soft terminals to enhance board flex sensitivity. The package size is 0805 (2012 metric), measuring 2.00mm x 1.25mm x 1.30mm. This specific variant includes a nickel barrier and functions as a three-terminal EMI filter.

Feature Summary

• Integrates FlexiCap™ technology with soft terminations to reduce stress on the substrate during board flexing.
• Functions as a three-terminal EMI filter to suppress electromagnetic interference in high-frequency circuits.
• Utilizes X7R dielectric characteristics for stable performance across a wide industrial temperature range.

Applications

• Board-flex sensitive electronic assemblies
• High-reliability circuit protection
• EMI filtering in communication modules

Procurement Notes

Verify the exact part number against official manufacturer documentation to confirm the presence of the nickel barrier and three-terminal configuration, as these are critical for EMI filtering functionality. Ensure compatibility with RoHS3 standards if required by your assembly process. Cross-reference datasheets for specific handling instructions related to the soft termination structure to prevent mechanical damage during placement.

Selection Notes

Select this component when board flex resistance is a primary design constraint alongside EMI suppression requirements. The combination of X7R dielectric and FlexiCap™ technology makes it suitable for rigid-flex or flexible PCB applications where standard MLCCs might fail due to mechanical stress. Consider the 25V rating and 22nF value relative to the specific signal filtering needs of the target circuit.
