1806Y0250223MJTE07

Overview

The Knowles Syfer 1806Y0250223MJTE07 is a surface-mount multilayer ceramic capacitor (MLCC) designed for high-frequency applications. It features a 1806 (4516 metric) case size with a capacitance of 0.022 µF and a voltage rating of 25 VDC. The component utilizes X7R dielectric material, providing stable performance across a temperature range of -55°C to +125°C. It incorporates a three-terminal EMI filter architecture with FlexiCap technology and a nickel barrier, offering enhanced electromagnetic interference suppression and mechanical reliability in sensitive board-flex environments.

Feature Summary

• Three-terminal EMI filter structure for superior noise suppression
• FlexiCap flexible terminations to reduce mechanical stress
• Nickel barrier layer for improved solderability and reliability

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• EMI suppression in communication equipment

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct termination style and packaging configuration. Confirm RoHS compliance status and specific environmental certifications required for your assembly process. Cross-reference the Mouser or DigiKey catalog numbers with the original datasheet to validate availability and lead times directly from authorized sources.

Selection Notes

Select this component when board flex sensitivity is a primary concern due to its flexible termination design. The three-terminal configuration provides better high-frequency performance compared to standard two-terminal MLCCs. Ensure the 1806 footprint matches the PCB layout constraints and that the 25V rating exceeds the maximum circuit voltage with appropriate derating margins.

Part Context

This component belongs to the Knowles Syfer FlexiCap series, which specializes in capacitors with soft terminations to prevent pad lifting during thermal cycling or mechanical stress. The Y prefix indicates the 1806 case size, while the MJTE07 suffix denotes the specific termination and packaging details defined by the manufacturer.

Replacement Considerations

Direct substitutes must match the 1806 footprint, 0.022 µF capacitance, 25V rating, and three-terminal EMI filter topology. Verify compatibility of the FlexiCap termination style if mechanical stress relief is critical. Standard two-terminal replacements will not provide equivalent EMI filtering performance.
